Description

  The present invention relates to an erroneous mail transmission prevention system, an erroneous mail transmission prevention method, and an erroneous mail transmission prevention program for preventing an electronic mail, particularly an electronic mail attached with a file having business data.

In recent years, e-mails have been used for various business communications, and e-mails have been used in place of communication means such as mail, fax, and home delivery for business communications not only within the company but also outside the company. There are many cases.
In addition, business processing is also made paperless, and there is an increasing number of cases where business data processed by a computer system is handled as a file without being printed on paper.

At this time, in the case of communication means such as mail, fax, and home delivery, the file data must be printed on paper or the file must be stored in a portable storage medium. Can be handled as an attached file.
In addition, e-mail can be transmitted to a destination simply by operating a personal computer at a desk, for example, and is extremely convenient.

However, when an operator uses an e-mail client software on a personal computer and attaches a file storing business data to an e-mail to a customer outside the company, for example, the following mistake is made: May occur.
When creating an e-mail, an e-mail address is mistaken when a mail address of a destination is selected from e-mail addresses stored in, for example, an address の of the mail client software, or when an e-mail address is entered from a keyboard.

When attaching a file to an e-mail, the file to be attached is incorrect.
When copying a fixed phrase into the body of an email, make a mistake in the fixed phrase.
The above-mentioned mistakes may occur. Especially when an item or the like is selected with the cursor using the GUI, an adjacent item is specified depending on the timing of moving the cursor and the timing of clicking. In some cases, the above-described mistakes cannot be completely eliminated as long as a person operates.

  However, if an e-mail is attached with a business data file, for example, if the destination is wrong, there is a risk of data leakage, and a careless mistake may have a serious result. In addition, if an incorrect email address is entered using the keyboard, there is a high possibility that the wrong address does not exist, and the email will not be delivered anywhere, and there may be no actual harm. In the case of wrong selection of the e-mail address in the address ア ド レ ス, the address entered by mistake is basically present, and the actual harm is surely generated.

Therefore, in order to prevent the erroneous transmission of the email based on the error as described above, the email sent from the mail client software is temporarily accumulated and processed as follows before being sent to the destination. It has been proposed to do so (see Patent Document 1).
The weight value is calculated from the contents of the email text temporarily stored and the type of data attached to the email, and the threshold value based on the relationship between the email sender and destination is calculated. If the value is below the threshold, the stored e-mail is sent to the destination, and if the weight value exceeds the threshold, a warning e-mail is sent to the source without sending the accumulated e-mail to the destination. .
As a result, for example, it is possible to prevent with high probability that a mail sent to a business customer is erroneously sent to a friend.

JP 2006-59297 A

However, for example, when it is necessary to send business mails to a plurality of customers, there is a possibility that the weight value is not greatly different by the method shown in Patent Document 1, It may not work. In particular, when the customers are the same type of business, and the same text or the same kind of data is attached, the determination becomes difficult.
In addition, when a mail is erroneously transmitted between a plurality of customers, there is a possibility of losing trust from both the real transmission destination customer and the erroneous transmission destination customer, resulting in a great damage.
Therefore, instead of reducing the erroneous transmission stochastically as in the conventional example, it is impossible to make an erroneous transmission reliably, or it is an erroneous transmission by any chance. It was desired to make the state incapable of being opened.

  The present invention has been made in view of the above circumstances, so that an operator's operation is not required for setting a destination mail address and setting a transmission file to be attached, so as not to cause an operator's operation error, and To provide an erroneous email transmission prevention system, an erroneous email transmission prevention method, and an erroneous email transmission prevention program in which a plurality of checks are performed so as to reliably prevent disclosure of data in a file at an erroneous transmission destination and an erroneous transmission destination. Objective.

In order to achieve the above object, the erroneous mail transmission prevention system according to claim 1,
Files that are generated by a business processing system that performs business processing for multiple customers and that are sent to each customer, and that are classified into multiple types according to the contents of this data, are attached to e-mails as transmission files And when sending to each customer individually, it is an email mistransmission prevention system for preventing erroneous transmission to send the transmission file to the wrong destination,
Unlike for each customer which is the destination of the transmission file and the transmission file storage device that stores a different directory for each type,
Transmission file directory information in which a plurality of types of transmission files can be generated for each customer as the business processing system, and the types of the customer and the transmission file are associated with a directory in which the transmission file of the transmission file storage device is stored A transmission file generation device for storing the generated transmission file in a directory of the transmission file storage device corresponding to the type of the customer and the transmission file;
Based on the operation of the first operator, an e-mail attached with a transmission file to be transmitted to the customer is created, and a mail transmission device that transmits the e-mail to the customer ;
The electronic mail created by the mail transmitting device is transmitted before being transmitted to the transmission destination, the electronic mail can be confirmed with a second operator different from the first operator, and the first A mail check device that enables the operator of 2 to send a reply mail indicating the confirmation result to the mail transmission device;
In the mail transmission device,
Destinations and e-mail address which the transmission file the for each type of the customer and the transmission file will send the transmission file is transmitted, the transmission file in the transmission file storage device is associated with each directory to be stored Destination information storage means for storing information;
A destination input means for causing the first operator to input a customer who is a transmission destination of a transmission file attached to the e-mail and a type of the transmission file ;
An electronic device that reads the mail address and the directory corresponding to the type of the customer and the transmission file input by the transmission destination input unit from the transmission destination information storage unit, and uses the read mail address as the transmission destination address. E-mail creating means for creating a mail and attaching the transmission file stored in the read directory of the transmission file storage device to the created e-mail;
E-mail confirmation transmitting means for transmitting the e-mail created by the e-mail creating means to a mail check device;
A transmission operation means for enabling an operation of transmitting the email created by the email creation means to the customer ;
The transmission operation until receiving a reply mail indicating whether or not to permit transmission of an electronic mail is received as a confirmation result of the electronic mail from the mail check device, and until a reply mail indicating permission to transmit the electronic mail is received Regardless of the operation of the transmission operation means so as to invalidate the operation to the means, the transmission of the e-mail to the destination is prohibited, and when a reply e-mail indicating permission to send the e-mail is received, And an e-mail transmission unit that validates an operation to the transmission operation unit and transmits an e-mail created by the e-mail creation unit to the destination according to an operation of the transmission operation unit.

In the first aspect of the invention, it is assumed that the transmission file is stored in a different directory for each transmission destination of the transmission file in the transmission file storage device. By simply inputting a destination, an e-mail with a destination e-mail address is created, and a transmission file to be sent to the destination is attached to the created e-mail.
Therefore, if the correct transmission file is stored in the correct directory of the transmission file storage means, it is reliably prevented that the transmission file is transmitted to the wrong destination.

  Here, the transmission destination is input as an operator's operation, so there is a possibility that the transmission destination entered by the operator may be wrong. In this case, an email is created with the wrong email address of the transmission destination, and the mistake is made. Since the transmission file to be transmitted to the transmission destination is attached to the electronic mail, the transmission destination to which the transmission file is to be transmitted and the mail address of the transmission destination are not wrong. In other words, there is a possibility that an e-mail is transmitted at a timing when the e-mail should not be transmitted, but a transmission file is not transmitted to a wrong transmission destination where the transmission file should not be transmitted.

Further, in this example, another operator (second operator) different from the operator (first operator) who performs the transmission operation before the e-mail with the transmission file attached is transmitted to the transmission destination. It will be checked, and erroneous transmission of the transmission file can be reliably prevented by the double check.
In addition, since a check request to other operators and a check result can be received by e-mail, the check operation is facilitated.
In addition, if you do not ask other operators to check and the check result does not permit sending of e-mail, you cannot send e-mail, so you do not have to check e-mail with a third party The e-mail can be prevented from being transmitted.

  The transmission destination and the mail address of the transmission destination may correspond one by one, but may correspond one by one. That is, here, the transmission destination may refer to a corporation such as a company (company), for example. When the transmission destination is a corporation, the email address of the transmission destination is an email address that represents the corporation, , It may be the email address that represents each department or the email address of the person in charge of each department, and the destination that receives the transmission file to be sent may be multiple departments or multiple persons in charge Therefore, a plurality of mail addresses may be set as the transmission destination of one transmission file.

For example, when a history file such as various logs automatically stored in a computer system is periodically transmitted to a transmission destination, the generated transmission file is stored in a directory corresponding to the transmission destination of the transmission file storage device. Thus, erroneous transmission of the transmission file can be prevented.
The contents of the transmission file are not limited to those automatically generated by the computer system. For example, the operator designates a transmission destination, causes the transmission file generation device to generate an empty transmission file, and stores it in a directory corresponding to the transmission destination of the transmission file storage device, and then stores the transmission destination of the transmission file storage device. Data may be input to a transmission file stored in the directory.

  Regardless of whether the data in the send file is automatically generated by the computer or manually entered, the computer automatically moves the data entered in other files to the send file. Even those that have been automatically moved by a computer to the transmission file may be used. However, since the transmission file is automatically generated by the computer corresponding to the transmission destination and stored in the directory of the transmission file storage device corresponding to the transmission destination, the transmission file is erroneously stored in a directory that does not correspond to the transmission destination. This can be prevented.

By at least automating the process of storing the transmission file in a directory corresponding to the transmission destination of the transmission file storage device, thereby preventing the transmission file from being stored in the wrong directory of the transmission file storage device by an operator operation. Can do.
Thereby, erroneous transmission can be prevented in the step of storing the transmission file, the step of inputting the destination mail address in the electronic mail, and the step of attaching the transmission file to the electronic mail.

Further, the transmission file can be managed not only by the transmission destination but also by the type of the transmission file, and it is possible to prevent erroneous transmission of different types of transmission files even at the same transmission destination.
For example, when there are daily reports, weekly reports, and monthly reports as business reports, these can be distinguished as the types of transmission files. In addition, it is possible to distinguish between a normal business report and an abnormal report.

The system for preventing erroneous mail transmission according to claim 2 is the invention according to claim 1,
Access restriction determination means for determining whether or not a restriction for prohibiting a third party different from the transmission destination from opening the transmission file is applied to the transmission file by encryption on the transmission file;
When the access restriction determination unit determines that the restriction is not applied to the transmission file attached to the email created by the email creation unit, the email transmission unit transmits the email. The electronic mail transmission prohibiting means for prohibiting is provided.

In the invention according to claim 2, for example, when a third party cannot access the transmission file by setting a password or the like, an e-mail to which the transmission file is attached is sent. By preventing transmission, for example, even if the transmission file is mistakenly transmitted to a partner who does not know the password for accessing the transmission file, the transmission destination cannot access the transmission file. Even if data is transmitted to the wrong partner, data leakage can be prevented.
In other words, since an electronic mail cannot be transmitted unless an access restriction is applied to the transmission file, even if erroneous transmission is performed, damage can be minimized.

In the invention according to claim 1 or 2, the erroneous mail transmission prevention system according to claim 3
Without providing a function to change the mail address of the transmission destination of the electronic mail created by the electronic mail creation means and the attached transmission file by the first operator in the mail transmission device, The change of the mail address of the electronic mail to be transmitted and the change of the transmission file are prohibited.

In the invention described in claim 3, when the operator inputs the transmission destination, the mail address to which the transmission file is to be transmitted and the transmission file to be transmitted are determined as described above. Therefore, it is possible to reliably prevent erroneous transmission due to an erroneous operation of the operator when transmitting the transmission file, and to prevent the operator from intentionally transmitting erroneously.
In other words, the operator's operation is basically only an operation for deciding to transmit a transmission file to a predetermined transmission destination. This determines the e-mail address and the transmission file to be transmitted. In addition, it is possible to prevent erroneous transmission by the operator performing extra operations.

The email erroneous transmission prevention system according to claim 4 is the invention according to any one of claims 1 to 3,
The transmission file storage device is provided with a directory for storing transmitted transmission files,
In the mail transmission device, the transmission file attached to the electronic mail transmitted by the electronic mail transmission means is transmitted from the directory in which the transmission file before transmission is stored in the transmission file storage device. Transmission file moving means for moving to a directory for storing transmission files is provided.

  In the invention according to the fourth aspect, since the file once transmitted is moved from the directory corresponding to the transmission destination of the transmission file storage device to the directory already transmitted, the transmission file is mistakenly returned after transmission of the transmission file. Even if the transmission operation is performed, the transmission file does not exist in the directory corresponding to the transmission destination, and the transmission file cannot be transmitted. Therefore, double transmission can be prevented.

In addition, when the setting is such that a plurality of transmission files are sequentially stored in the directory, the previously transmitted file is moved to the transmitted directory, and the next created transmission file is set as the transmission destination. Since the setting can be stored in the corresponding directory, it is possible to prevent the transmission file from being mistakenly handled among a plurality of transmission files to be transmitted to the same transmission destination although the creation time is different. For example, when a transmission file that is periodically transmitted is handled, it is possible to prevent a past transmission file from being erroneously transmitted.
When it is necessary to retransmit the transmission file, the transmission file is not deleted but only moved to the transmitted directory, so it is possible to retransmit the transmission file in the transmitted directory. .

  According to the present invention, an operator who performs an operation of attaching a transmission file to an e-mail and transmitting it to a transmission destination basically performs only an operation of designating (inputting) the transmission destination. The destination mail address and the transmission file attached to the e-mail are determined. Further, the created e-mail is checked by an operator different from the operator, and the e-mail cannot be transmitted until it is determined that the e-mail can be transmitted. For these reasons, it is possible to reliably prevent erroneous transmission of electronic mail.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an outline of an erroneous mail transmission prevention system (business system) according to an embodiment of the present invention.
In the present invention, in a company entrusted with data management work from a plurality of customers, an error in the processing of the data management work is extracted, an error report file (transmission file) is created, and this transmission file is converted into an e-mail. It is attached and transmitted to the customer.

  The erroneous email transmission prevention system as a business system in the company includes a business processing system (transmission file generation device) 1, which is dedicated from outside each office of each company serving as a customer. Data storage, data management, processing according to an input command, and transmission of processing results are performed according to data and commands sent via a line or the Internet. This business processing system is basically a business processing system provided with a well-known database, and performs, for example, data processing in inventory management of manufacturers, wholesalers, trading companies, etc. that sell products.

  A mail erroneous transmission prevention system as a business system including such a business processing system 1 includes the business processing system 1, a transmission file storage device 2 for storing a transmission file output from the business processing system 1, The business processing terminal 3 that can input / output data to / from the business processing system 1 and input commands, and that can read and write the transmission file in the transmission file storage device 2 and attach the transmission file to an e-mail Mail sending terminal 4 for performing work to be sent, mail check terminal 5 for checking e-mail before sending e-mail from the mail sending terminal 4 to the customer's destination, and mail sending terminal 4 and the mail server 6 for sending and receiving mail between the outside and the mail sending terminal 4 to send e-mail And an in-house Web server 7 for the corporate intranet that allows browsing the Web page for the form e-mail from the mail transmission terminal 4, which is used to.

  Here, the business processing terminal 3, the mail transmission terminal 4, and the mail check terminal 5 are basically composed of a computer system such as a personal computer, and applications for realizing the functions of the terminals described later are installed. In addition, it is only necessary to be connected to an in-house LAN (including an intranet), and one computer may have functions as the business processing terminal 3, the mail transmission terminal 4, and the mail check terminal 5. However, it is preferable that a plurality of the computers are provided so that a plurality of operators can operate simultaneously. On the other hand, each computer need only have an application that implements a function required by an operator operating the computer, only the business processing terminal 3, only the mail transmission terminal 4, and only the mail check terminal 5. It may not work.

The mail server 6 and the Web server 7 are also personal computers or server computers in which a server OS that basically realizes a server function is installed. That is, the mail server 6 and the web server 7 are computer systems in which the mail server software and the web server software are installed, and the functions of the mail server 6 and the web server 7 may be mounted on one computer. The mail server 6 and the Web server 7 may be composed of different computers.
Each of the above terminals and servers is provided with an output means such as a display and a printer and an input means such as a keyboard and a mouse as a computer system. Hereinafter, the display, keyboard, and mouse are used for display and input. Although description may not be given, in practice, display is performed on a display, and input using a GUI is performed by display on the display and operation of a keyboard or a mouse.

The business processing system 1 is a server computer system that functions as a server having functions such as a database, for example.
The business processing system 1 is, for example, in inventory management, when there is a product name or product number that does not exist in the product name or product number (code) or the like in data input such as an order (issue) or an order (goods receipt). When there is an error in data entry, when the number of goods issued is larger than the number of stocks, when the number of stocks is less than the preset minimum stock number, or when data processing based on program bugs etc. When an error occurs, the occurrence of the error is stored as an error history, and the error history data is output to the transmission file storage device 2 as an error report file (transmission file).

  The business processing system is a system for business processing using a database as described above. However, in the present invention, a transmission for outputting and storing an error report file as a transmission file in the transmission file storage device 2. Any computer system may be used as long as it has a function as a file generation device.

Further, the transmission file is not limited to the above-described error report file, and basically may be a file automatically generated by the business processing system. Note that the transmission file generated at this time may have no content, or may manually input data to the transmission file generated and stored in the transmission file storage device 2.
Then, the business processing system 1 creates an error report file as a transmission file for each of a plurality of customers (transmission destinations). When generating an error report file, an error report file is created with a file name based on transmission file directory information stored in advance and a preset rule, and a predetermined file in the transmission file storage device 2 is created. Store in directory.
That is, the file name of the error report file includes information indicating the customer name (transmission destination name), the creation date and time, and the report type. Each of these items may be coded, for example, and a file name may be created from a code corresponding to each item. In this example, the company name, report type name and date of the destination customer are added to the file name, the company name of the customer is company a, the report type is report α, and the date is 2007. In the case of April 1, the file name of the transmission file is “a company report α20070401”. Here, the report α indicates a daily error report file output every day.

  Also, instead of including this information in the file name, it is also possible to include these data in the file property data, and the general owner of the file property is used as the customer name. The date and time may be used as the creation date and the title may be the report type. Note that the report type (the type of transmission file) is the type of report created by the business processing system, but it may be the above-mentioned error report, business report, etc. There may be a type of daily report (daily report), weekly report (weekly report), monthly report (monthly report), or the like. Therefore, the type of the transmission file is a type based on the contents of the file, and is not a type of file form such as an image file or a text file. However, the form of the file may be different depending on the contents of the file. .

  Note that the storage device of the business processing system 1 stores a data table (transmission file directory information) in which an algorithm for assigning a file name, a company name of each customer, and a transmission file type are stored. Based on this, a file name is generated.

Further, the transmission file is, for example, a file for a general and widely used application so that it can be easily read by the customer side, for example, a file for an application such as a word processor or a spreadsheet. Yes.
In addition, these applications are provided with a password setting function, and the business processing system uses this application to set a predetermined password for each customer when a transmission file is generated. It has become.

Note that when the password is set, the transmission file is preferably encrypted. In other words, the application preferably has an encryption function, and is preferably encrypted by a preset encryption process when setting a password.
The password is stored in the business processing system as a data table (transmission file directory information) in which a customer name (transmission destination name) to be a transmission destination or a customer name and a type of transmission file is associated with a password, for example. Although stored in the device, this data table is preferably stored encrypted.

In addition, apart from the application that creates the error report file, a dedicated encryption application may be used to encrypt and set a password.
In this case, an encryption key (for example, a public key, a secret key, etc.) may be used, and a key for each customer may be set and a password may be set.
In this case, the file name of the key file corresponding to the customer name or the customer name and the type of transmission file is registered in the data table, and the business processing system uses the data table to transmit a predetermined type of transmission file. Encrypt the transmission file with the key file and password corresponding to the destination name.

  The transmission file here is, for example, a daily error report file, which stores an error history for one day on the day before the day when the daily error report file is sent to the customer for daily reports. Thus, for example, it is stored in the transmission file storage device 2 from the business processing system 1 at the time when the business of the customer is completely completed or at a predetermined time such as 24:00. At this time, as the transmission file directory information, the transmission file is stored in the transmission file storage device based on the data table in which the transmission destination (customer) or the transmission destination and the type of transmission file is associated with the directory of the transmission file storage device 2. 2 is stored in the directory corresponding to the transmission destination (transmission destination and transmission file type).

  Further, the business processing terminal 3 is connected to the business processing system 1 and the transmission file storage device 2 via the LAN. The business processing terminal 3 is not a mere terminal, but is a computer such as a personal computer as described above. It is preferable that at least the business processing terminal 3 is connected to the business processing system 1 to perform processing related to errors. In addition to functioning as a client of a server as a database, the above-described application for creating a transmission file is installed so that the transmission file can be read and written.

  Here, when an error occurs in the business processing system 1 as described above, information indicating the occurrence of the error is input to the business processing terminal 3 from the business processing system 1. The business processing terminal 3 can request the business processing system 1 to display the error content so that the operator of the business processing terminal 3 can confirm the error content in the business processing system 1. It has become. Then, it is possible to deal with an error in the business processing system 1 from the business processing terminal 3. For example, when there is no corresponding part number due to an error based on the above error, It is possible to perform processing such as searching for the product number from the input product name and correcting the product number, or checking the input contents by mail or telephone to the customer's office and correcting the product number.

  In the business processing system 1, when an error handling process from the business processing terminal 3 is performed, the error handling process is also associated with the customer name information and stored as a history. The correspondence history is also written in the error report file. Further, in the business processing terminal 3, it is possible to add a comment to the error history, and the operator can write a comment for the customer. This comment is also written to the error report file.

In addition, the business processing terminal 3 is installed with an application for creating the above-described error report file (transmission file), and it is also possible to directly describe comments for customers in each error item of the transmission file. Yes.
In addition, when an error report file is not correctly created due to an abnormality in the business processing system 1 itself, a new error report file can be created and stored in the transmission file storage device 2.

The transmission file storage device 2 is a storage such as a hard disk on an in-house LAN, for example, a file server or a NAS (Network Attached Storage). The transmission file storage device may be a storage device built in the mail transmission terminal 4, for example.
The transmission file storage device 2 has a hierarchical directory structure as is well known. A directory (folder) for each customer handled by the business processing system is provided, and the business processing system 1 stores the error report file created for each customer as described above in the directory for the customer. .
The directory for each customer name (transmission destination name) in the transmission file storage device 2 may be further hierarchized and stored in a different directory for each report type or date. Here, the transmission file storage device 2 is provided with a directory for each customer, and a directory for each type of transmission file is provided below the directory for each customer.

  The transmission file storage device 2 is formed with a directory for transmitted files for storing a transmission file after being attached to an e-mail and transmitted based on a script (program) of a form mail described later. When a file is attached to an e-mail and transmitted, the script is moved from the customer-specific directory to the transmitted file directory by the processing of the script. In addition, it is preferable that the directory for transmitted files is also separated for each customer. In this example, a directory (for example, transmitted) in which a transmission file that has been transmitted is stored is formed below the directory in which the transmission file is stored.

The mail transmission terminal 4 is a computer system such as a personal computer, for example, and is installed with well-known browser software and an application that creates the above-described error report file.
Note that well-known mail client software is installed in the mail transmission terminal 4, but the above error report file is transmitted to the customer without using the mail client software. The form mail on the page is used.

The form mail function to be described later may be realized by the mail transmission terminal 3 by a script (for example, JAVA (registered trademark) script) operating on the browser, but in this example, in the computer system as the Web server 7, the CGI (Common Gateway Interface), SPA (Active Server Pages), PHP (PHP: Hypertext Preprocessor), and other scripts are executed. Therefore, the mail transmitting device of the present invention is composed of the mail transmitting terminal 4, the Web server 7, and the mail server 6 that acts as an intermediary for sending and receiving electronic mail.
Then, when the e-mail transmission processing web page stored in the web server 7 is opened by the browser in the e-mail transmission terminal 3, the e-mail transmission processing web page includes an e-mail as shown in FIG. This is a screen for selecting a customer name (destination name) to be transmitted and a file type (for example, report α, report β) to be transmitted.

  For example, on the display of the mail transmission terminal 4, a plurality of buttons are displayed on the Web page, and a customer name (transmission destination name) and a type of transmission file are displayed on each button. Here, for example, buttons such as a report α (daily error report) of the customer a, a report β (business report) of the customer a, a report α of the customer b,.

When an operation for selecting a button displaying the name of the customer to be processed and the type of transmission file is performed from these buttons, the operator switches to a so-called form mail web page stored on the web page. It has become.
As shown in FIG. 3, in the form mail Web page, the mail address column (destination address) of the selected customer, the subject field of the e-mail, and the attached file attached to the e-mail (error report) File name field of the transmission file to be transmitted, the directory name of the attached transmission file in the transmission file storage device 2, and transmission of the transmission file storage device moved when the error report file is transmitted as described above The directory name of the destination of the completed file (the above-mentioned transmitted directory) and the mail address column of the mail check terminal are displayed.

  The above display contents are displayed in an unchangeable state in which the operator's operation is not accepted on the form mail Web page. The directory name and file name may be displayed as a so-called full path file name, and the directory name may be displayed hierarchically before the file name. The displayed data is stored, for example, as a data table as transmission destination information stored in the Web server 7, and is stored in association with a combination of the transmission destination and transmission file type corresponding to each button. Has been.

That is, the Web server 7 functions as a transmission destination information storage unit that stores transmission destination information that associates a mail address with a directory in which a transmission file of the transmission file storage device is stored for each transmission destination. Further, the destination storage means includes at least one of a mail address to which the transmission file is transmitted for each destination and type of the transmission file, a directory in which the transmission file of the transmission file storage device is stored, and a file name of the transmission file. The destination information associated with the copy is stored. The transmission destination information may be stored in the mail transmission terminal 4.
From the above, when the destination and the type of transmission file are specified by operating the button on the Web page described above, the data to be displayed is extracted from the data table.

  That is, in the storage device of the Web server 7, the customer's e-mail address as the transmission destination and the electronic mail corresponding to the customer name and the type of transmission file input as described above by each of the buttons selected above The subject of the mail, information on the file name of the transmission file attached to the e-mail, the directory in which the transmission file is stored, the directory to which the transmission file is moved after transmission, and the transmission file are attached as described below The mail address of the mail check terminal used by the general operator who checks the e-mail before transmission and the text of the e-mail to be transmitted (only the fixed part) are stored as transmission destination information.

Here, in correspondence with each button, the mail address of the person in charge or the department in charge to be received is associated, but the number of associated mail addresses is not limited to one, and an e-mail is transmitted to a plurality of persons in charge. It may be set. In other words, the destination (customer) and the destination email address do not necessarily have a one-to-one relationship, and a plurality of destination names may correspond to one customer.
Further, even for the same customer, different mail addresses may be registered when the types of transmission files are different.
In this example, a plurality of e-mail addresses are stored in association with the combination of the transmission destination (customer name) and the type of transmission file.

  The transmission file is not directly associated with the button. When the button is selected, the directory of the transmission file storage device 2 in which the transmission file corresponding to the button is stored is determined. Further, a part indicating the customer name (transmission destination name) and transmission file type information in the transmission file name is determined.

And, for example, the above-mentioned transmission file is limited by the customer name (destination name) of the file name and the portion indicating the information of the transmission file type, and the file with the newest date and time is selected, and this is transmitted. It is good also as what.
In this example, only one daily error report file is output from the business processing system 1 to the transmission file storage device 2 for each date. In this example, the daily error report file includes the date of the previous day. The file to be sent is selected.

That is, in this example, since only one file is actually created once a day for each customer as described above, the date / time data included in the file name is only the year / month / day. It is not included. In this example, a transmission file including the date information of the previous day in the file name is selected.
Basically, the directory in which each transmission file is stored has only a predetermined destination transmission file at a predetermined transmission destination. It is also possible to select the transmission file based on the latest creation date, but here there is a possibility that some file may be mixed in by manual operation etc., so the destination name of the file name, It is confirmed whether or not the portion indicating the file type information corresponds to the transmission destination and file type input by the button operation.

The form mail stores a text as a standard text. Here, the standard text is different depending on whether an error exists in the daily error report or not.
Then, the operator selects a fixed sentence on the Web page of the form mail. Here, for example, before the operator performs mail transmission processing at the business processing terminal 3 (or the mail processing terminal 3 if the mail transmission terminal 4 has the function of the business processing terminal 3), Have confirmed. As a result, the operator knows whether or not there was an error on the previous day, and the operator can select the standard text that will be the email text if there is no error and the standard text that will be the email text if there is an error. It has become.

Then, the operator selects either a fixed sentence with an error or a fixed sentence without an error based on the number of errors yesterday in the business process of the corresponding customer.
Here, the selection is performed by selecting a part of the fixed sentence.
For example, the standard text without error is written as “There was no alert (error warning) for the previous day.”, And the standard text with error was written as “Send the alert list for the previous day.” It has become.

And on the Web page, “alerts for the previous day” of the above-mentioned fixed phrases are fixedly displayed, and after that there are two items: “There was no” and “Send a list”. The pull-down menu is displayed, and the text is determined from the two fixed sentences when the operator selects it.
In addition, there is a part that follows the above-mentioned “There was no” and “Send a list”, and “There was no” and “Send a list” are displayed. It is displayed on the lower side.
In addition, as described above, the fixed sentence is determined by whether there is an error or no error. If no error is set by default, the fixed sentence without error is not selected by the operator. It will be in the selected state.

  In this example, the operator's operation is intervened in the selection of the fixed phrase described in the text, but whether or not there is an error can be output from the business processing system 1 as data. As the processing of the above-mentioned form mail script, it may be determined whether or not there is an error, and one fixed sentence may be selected from a plurality of fixed sentences that become the mail body based on the determination result.

  In addition, when the mail text is determined based on the presence or absence of an error, the part after the selected export part of the mail text is also displayed. May be changeable by the operator. That is, the setting may be such that the text may be deleted, rewritten, or added except for the first part of the fixed phrase. However, in this example, the text cannot be rewritten.

In this example, the transmission file is a daily error report file as described above, and originally consists of error log (error history) data, which is not necessary when there is no error. In this example, the error report file is stored as a transmission file by the business processing system 1 in the transmission file storage device 2 even if it does not exist. Therefore, as it is, an error report file indicating no error is attached to the e-mail and transmitted to the customer. However, if there is no error, an error report file is not required if the email body contains no error. Therefore, in this example, when the text without error is selected when selecting the text as described above, the attachment of the transmission file is canceled.
In addition, the form mail Web page has a column indicating whether or not an attached file is attached. If a fixed phrase without error is selected, this column displays that there is no attachment. If a fixed phrase with error is selected, it is attached. Yes.

  In addition, when the file with the above file name is read from the transmission mail storage device, when there is no file with the predetermined file name in the predetermined directory, there is no transmission file as shown in FIG. A warning display indicating that is displayed in a floating window on the Web page. In this example, even when a transmission file is not attached as described above, the transmission file is read out so that it is not attached to the e-mail when the e-mail is finally transmitted.

As a result, whether or not the transmission file is attached, the following check is performed. Even when the transmission file is not attached, the attachment file check may clarify processing problems. In addition, when an e-mail is transmitted without attaching a transmission file, the transmission file that has not been attached is moved to the transmitted directory in the transmission file storage device 2.
In addition, when the attached file does not exist, for example, when another operator has already performed transmission processing, the transmission file is moved to the transmitted directory, and the transmission file does not exist in the corresponding directory. Or the transmission file is not created due to some error.

  Further, a confirmation transmission button and a customer transmission button are displayed on the Web page of the form mail. The confirmation send button checks the e-mail sent to the customer to a person who is a third party other than the operator who is sending the e-mail, in this case the general operator who is the general manager who manages the work of each operator. In order to receive the request, the process of transferring the e-mail before starting transmission to the customer is started.

Then, when the operator operates the confirmation transmission button, a confirmation e-mail in which the e-mail to be transmitted to the customer is attached to the e-mail address of the e-mail check terminal 5 instead of the e-mail address as the above-mentioned transmission destination. Sent.
In this example, when the above confirmation transmission button is operated, whether or not a password is set in the attached transmission file before the e-mail attached with the e-mail to be transmitted is transmitted to the mail check terminal 5. Is checked.

  When a transmission file is attached, if a password is not set, a floating window warning that a password is not set is displayed as shown in FIG. A button for selecting whether to set or cancel the mail transmission process is displayed. At this stage, the password is not set when the corresponding transmission file stored in the transmission mail storage means is opened and modified by the operator operation or when the operator recreates the transmission file. In addition, the operator forgets to set a password.

Therefore, if it is determined that the operator's operation on the transmission file is correct, a password may be set, and if there is any doubt, the process may be stopped to verify the transmission file.
Here, as shown in FIG. 6, when the operator sets a password, there is a possibility that the operator may mistake the password, but whether the password is correct is determined by the general operator who operates the mail check terminal 5. It will be checked as described below.

  When a password is set in the transmission file, an e-mail to be sent to the customer is attached as described above when the processing is continued as shown in FIG. 7 and when a password is set in the transmission file. The sent e-mail is transmitted to the e-mail address set in the e-mail client software installed in the e-mail check terminal 5.

  The customer transmission button is in an invalid state at normal time, and even if the operator operates the customer transmission button, the above-mentioned e-mail to be transmitted to the customer is not transmitted to the customer. Then, when the operator operates the disabled customer transmission button, if it is before the confirmation transmission button operation, as shown in FIG. 8, a floating window is displayed prompting the user to press the confirmation transmission button. It has come to be.

In addition, after the confirmation send button is operated, a floating window is displayed indicating that the confirmation is on standby. It should be noted that after the operation of the confirmation transmission button, the customer transmission button is still in an invalid state when an approval reply has not arrived from the mail check terminal as will be described later.
Also, as shown in FIG. 9, even when a non-approval reply arrives from the mail check terminal, the customer send button remains invalid. In this case, the non-approval is performed by checking the e-mail sent to the customer. Therefore, the electronic mail cannot be transmitted, and the process is terminated. In this case, the operator closes the floating window and closes the Web page, for example, makes a meeting with the general operator, corrects the transmission file, etc., and restarts the process.

  Then, as shown in FIG. 10, when an approval reply arrives, the customer send button becomes valid based on the script on the Web page. Here, the script on the web page checks the reception of the e-mail after the search for the confirmation transmission button, and when the e-mail is received, checks whether or not the e-mail sent by the confirmation transmission button is a reply, In the case of a reply, it is checked whether the code written in the subject or text indicates approval or non-approval, and in the case of approval, the confirmation transmission button is validated.

Whether the confirmation send button is valid or invalid means that when the confirmation send button is operated, an e-mail transmission process to be sent to the customer or a display process indicating invalidity as described above is performed. It becomes.
When the confirmation transmission button becomes valid, for example, the display color of the confirmation transmission button changes, and the operator confirms that the confirmation transmission button is valid. When the operator presses the confirmation transmission button, as described above, The e-mail with the text determined as described above is transmitted to the determined mail address of the destination. At this time, when attaching the transmission file as described above, the electronic mail is transmitted with the transmission file determined as described above attached.

  Further, in the transmission file storage device in the script processing of the Web page, the transmission file transmitted is moved from the directory for each customer transmission file to the directory that has been transmitted. As a result, when another operator tries to send an e-mail with the same send file attached to the e-mail again, there is no send file in the directory before sending, so there is no send file error. Thus, the transmission process is terminated.

  As described above, even when a transmission file is not attached, a transmission file indicating no error is stored in a predetermined directory of the transmission file storage device. Therefore, when an e-mail is transmitted, the transmission file has already been transmitted. Change to the directory. Also in this case, if another operator makes a mistake and tries to send the same e-mail again, an error indicating that there is no transmission file in the predetermined directory results in an error indicating no transmission file, and the transmission process is terminated. It will be.

The sent e-mail is received from the mail server 6 via the Internet to the destination mail server. However, due to a change in the destination mail address or a trouble with the destination mail server. If the mail does not reach the destination mail server, an e-mail indicating that the e-mail has not been normally sent from the mail server 6 of the transmission source to the mail client software of the mail transmission terminal 4 Is output.
In this case, the e-mail indicating the error in which the e-mail address of the transmission destination, the subject, and the transmission date is described is received by the e-mail transmission terminal 4.
In this case, it is necessary to check the mail address of the transmission destination and perform the transmission process again. However, since the transmission file has already been moved to the transmitted directory, if the transmission process is performed as described above, It ends with an error that there is no transmission file. Therefore, it is necessary to restore the transmission file in the transmission file storage device 2, and it is necessary to perform processing for moving the transmission file from the transmitted directory to a predetermined directory before the movement.

  When the confirmation sending button described above is operated, mail client software is installed in the mail check terminal 5 and the confirmation e-mail transmitted from the mail sending terminal 5 is received via the mail server 6. become.

In the mail check terminal 5, a general operator (second operator), who is higher than each operator (first operator), is working, and when a check e-mail is received, the e-mail is received. The general operator opens the e-mail, for example, an HTML mail that can execute a script, and an e-mail to be transmitted to the customer is attached to the HTML mail.
For example, as shown in FIG. 11, the HTML mail is provided with a mail check button for opening an e-mail. When the mail check button is operated, the attached e-mail is opened. . As a result, the destination address, subject, and text of the e-mail can be viewed.

  It is also possible to open an attached file. For example, when an email is opened as described above, a button for opening the attached file is displayed on the email, and the attached file can be opened. Yes. If you specify to open the attachment file, the password is always set for the transmission file that becomes the attachment file as described above, so the same application that created the transmission file starts up, and depending on the application , The password input screen is displayed. Then, a display requesting input of a password is performed. Alternatively, when encryption software is used, the encryption software starts up first, and a password input is requested.

  Here, the general operator has some form of password data for each destination, and can input a password corresponding to the destination. Therefore, if the general operator opens the transmission file with the password corresponding to the transmission destination, the set password is correct. For example, when the operator sets the password as described above, the operator It is possible to check for mistakes.

The general operator checks the subject, transmission destination address, mail text, password of the attached transmission file, and the contents of the transmission file of the electronic mail transmitted to the customer.
The HTML mail is also a kind of form mail, and two buttons for transmitting a reply mail to the mail transmission terminal that has transmitted the check mail are displayed.

These buttons are an approval button and a non-approval button. When the approval button is operated, a reply mail in which a code indicating approval is described in the subject or text is transmitted to the mail transmission terminal 4, and when the non-approval button is operated A reply mail in which a code indicating non-approval is described in the subject or text is transmitted to the mail transmission terminal 4.
As described above, the general operator checks the e-mail sent to the customer, and if there is no problem, presses the approval button, and if there is a problem, presses the non-approval button. The mail check terminal 5 receives a confirmation e-mail via the mail server 6 and transmits a reply mail, and executes a script for HTML mail by the Web server 7. Consists of a mail check terminal 5, a mail server 6, and a Web server 7.

  The reply mail can be automatically confirmed for approval and non-approval by the script on the web page of the form mail, and read the code indicating approval or the code indicating non-approval described in the above subject or text, Approved (transmission permitted), non-approved (transmission prohibited) is determined. When the reply mail from the mail check terminal 5 is received as a reply of the above-mentioned HTML mail, the form mail Web page reads the subject or the body code of the reply mail. The customer send button on the form mail Web page is enabled. The reply mail may be received by the Web server 7 instead of being received by the mail transmission terminal 4.

Next, in the transmission of an e-mail to a customer, an erroneous mail transmission prevention process performed by executing an erroneous mail transmission program on the mail transmission device (mail transmission terminal 4, mail server 6, Web server 7) is illustrated in more detail. 12 and the flowchart of FIG.
Note that the erroneous mail transmission prevention method here is basically a virtual process on the browser, and is a combination of the mail transmission terminal 4 and the processes on the Web server 7 and the mail server 6. The processing on the browser will be described as processing performed at the mail transmission terminal 4.
The basic processing is the same whether the processing on the browser is performed by the mail transmission terminal 4 or the Web server 7.

First, in the mail transmission terminal 4, the operator designates the URL of a Web page for transmission processing of an e-mail to which a transmission file for a customer displayed on the display is attached (clicking on a shortcut icon), thereby causing the Web server 7. An operation of opening the above transmission processing Web page by the browser software of the mail transmission terminal 4 is performed.
Thereby, the mail transmission terminal 4 displays the transmission processing Web page shown in FIG. 2 (step S1).

As described above, the Web page displayed on the mail transmission terminal 4 includes a plurality of buttons displaying each customer name (transmission destination) and the type of transmission file. The operation to select is performed.
The mail transmission terminal 4 determines whether or not any button has been operated (step S2), and when operated, the data table stores data corresponding to the destination and the type of transmission file indicated by the operated button. Read from (destination information) (step S3).

  In the data table, corresponding to each button, the destination mail address, the subject of the email, the body of the email, the email address of the mail check terminal 5 used by the general operator checking the email, the email body Information that determines the file name of the transmission file, the directory of the transmission file storage means in which the transmission file is stored, the transmission file is stored, and the data based on the transmission destination corresponding to each button and the type of the transmission file These data are read out as follows. The file name is determined as described above based on information for determining the file name.

Next, the form mail Web page shown in FIG. 3 is displayed based on the information read from the data table (step S4).
Based on the information read as described above, the Web page stores a destination e-mail address (or a transmission name associated with the e-mail address at address 帖), a subject, and a transmission file in the transmission mail storage means. The directory name, the file name of the transmission file, the mail address of the mail check terminal, and the directory name in the transmission mail storage means moved after transmission of the transmission file are displayed in a state where they cannot be rewritten.

In addition, an e-mail body is displayed below these displays.
The export part of the e-mail body is displayed so that the export can be selected from the pull-down menu depending on whether or not there is an error as described above. Here, the above-mentioned “I did not exist” is selected, and The following text is displayed.

Next, it is determined whether or not there is a file having a file name based on information for determining the file name in the directory of the transmission file storage means (step S5).
When there is no transmission file, as shown in FIG. 4, a floating window that displays that there is no transmission file is displayed (step S6).
Next, it is determined whether or not the (OK) button displayed in the floating window has been operated (step S7).
If the button is operated, the process ends.

If there is a file, it is determined whether or not the pull-down menu of the text of the form mail has been operated (step S8).
When the pull-down menu is operated, the display of the standard sentence that is the text is changed based on the selected selection branch of the selection branches (step S9). When the same item before selection is selected, the previous display is redisplayed.

When the pull-down menu is not operated or when the display of the text is changed or redisplayed by operating the pull-down menu, it is determined whether or not the confirmation transmission button is operated (step S10).
If the confirmation operation button is not operated, it is determined whether or not the customer transmission button is operated (step S11), and if not, the process returns to step S8.
When the customer send button is operated, since the customer send button is invalid at this stage, a floating window that prompts the user to press the confirmation send button is displayed as shown in FIG. 8 (step S12).

Next, it is determined whether or not the (OK) button displayed in the floating window has been operated (step S13).
If the button is operated, the process returns to step S8.

If it is determined in step S10 that the confirmation operation button has been operated, it is determined whether or not a password is set for the transmission file stored in the above-described directory of the transmission file storage device (step S14).
If no password has been set, as shown in FIG. 5, since no password is attached, a floating window asking whether or not to assign a password is displayed (step S15). In this window, since two buttons, yes and no, are displayed, it is determined whether or not any of the buttons has been operated (step S16).

If it is determined that the button has been operated, it is determined whether the button is a Yes button or a No button (step S17). If the button is No, the process ends.
If the button is YES, a floating window serving as a password input screen shown in FIG. 6 is displayed (step S18).
Since the password input field, the OK button, and the cancel button are displayed in the window, it is determined whether any one of the buttons has been operated (step S19).

If it is determined that the button has been operated, it is determined whether the button is an OK button or a cancel button (step S20). If the button is a cancel button, the process ends.
If the OK button is pressed, the password input in the input field is set in the transmission file, and the process proceeds to step S24. If no password is entered in the input field when the OK button is operated, the process returns to step S18 again.

If it is determined in step S14 that a password has been set, a floating window is displayed as shown in FIG. 7 to indicate that the password has been set and whether to continue the process. It is displayed (step S21).
Since two buttons, yes and no, are displayed in this window, it is determined whether or not any of the buttons has been operated (step S22).
If it is determined that the button has been operated, it is determined whether the button is a yes button or a no button (step S23). If the button is no, the process ends.

  When the password is set in step S21 and when it is determined that the yes button is pressed in step 24, the confirmation HTML mail shown in FIG. 11 attached with the e-mail to be sent to the customer is checked by mail. It transmits to the mail address of the terminal 5 (step S24).

Next, it is determined whether or not a reply mail from the mail check terminal 5 has been received (step S25). Here, the system waits until a reply mail is received.
On the other hand, as described above, the mail check terminal checks the password of the transmission file, checks the destination mail address, checks the body text, etc., and operates the approval button or the non-approval button on the HTML mail. The approval reply mail or the non-approval reply mail is transmitted to the mail transmission terminal 4.

Thereby, in the mail transmission terminal 4, it is determined in step S26 that the reply mail from the mail check terminal 5 has been received.
Next, it is determined whether the received reply mail is approved or non-approved (step S26), and in the case of non-approval, a floating window indicating that it is non-approved is displayed as shown in FIG. (Step S27). Since an OK button is displayed in this window, it is determined whether or not the OK button has been operated (step S28). Then, if it is determined that the OK button has been operated, the process is terminated.

  If the approval is determined, a floating window indicating the approval shown in FIG. 10 is displayed (step S29). As a result, while the operator is waiting for a reply, it is possible to easily recognize that the e-mail to be transmitted to the customer can be transmitted even if other work is performed at the mail transmission terminal.

Since an OK button is displayed in the window, it is determined whether or not the OK button has been operated (step S30). If the OK button is pressed, the customer send button is validated. Then, the color of the customer send button is changed on the Web page of the form mail (step S31).
Next, it is determined whether or not the customer transmission button has been pressed (step S32).

  Actually, the operation of the customer transmission button is constantly monitored while the web page of the form mail is displayed, and the customer transmission button is operated as described above until the confirmation transmission button is operated. Then, a display prompting the user to operate the confirmation transmission button is performed, and after the confirmation transmission button is operated, a display indicating that a reply is waiting is displayed.

When the customer transmission button is operated, an e-mail is transmitted with the above-described transmission file attached to the above-mentioned transmission destination and the transmission file is stored in the transmission file storage device 2. In step S33.
However, as described above, in the daily error report, since no error is described in the transmission file that does not have an error, the text selected when there is no error when sending an e-mail. As an export, there was no alert for today, but when selected, the e-mail is sent without the send file attached to the e-mail. Also at this time, the transmission file is moved to the transmitted directory.

  According to the erroneous mail transmission prevention system, the erroneous mail transmission prevention method, and the erroneous mail transmission prevention program as described above, the erroneous mail transmission prevention system has different transmission files attached to the e-mail for each transmission destination. Based on the operation of the transmission file storage device 2 stored in the directory and the operator as the first operator, an e-mail attached with the transmission file to be transmitted to the destination is created, and the e-mail is sent to the destination A mail transmission device (mail transmission terminal 4, Web server 7 and mail server 6) to be transmitted is transmitted before the electronic mail created by the mail transmission device is transmitted to the destination, and the electronic mail is sent to the first Reply mail that can be confirmed by the general operator as the second operator different from the operator and the second operator indicates the confirmation result So that and a mail check unit (mail check terminal 5, Web server 7 and the mail server 6) that can be transmitted to the mail transmission device.

  The mail transmission device stores transmission destination information in which a transmission destination (customer) or a transmission destination and a type of transmission file are associated with a mail address and a directory in which the transmission file of the transmission file storage device is stored. A function as a transmission destination information storage means, and a transmission destination input means for causing the first operator to input a transmission destination or a transmission destination of a transmission file attached to the electronic mail and a type of transmission file The function and the e-mail address and the directory corresponding to the data input by the destination input means are read from the destination information, and an e-mail is created with the read e-mail address as the destination, and The sent e-mail stored in the read directory of the send file storage device 2 is sent to the created e-mail. Function and is provided as an electronic mail creation means to attach a file.

  In addition, the mail transmission device enables a function as an email confirmation transmission unit that transmits the email created by the email creation unit to the email check device, and an operation of transmitting the created email to the destination. A function as a transmission operation means, and a reply mail indicating whether or not to permit transmission of an email is received as a confirmation result of the email from the mail check device, and a reply mail indicating permission to transmit the email is received The email sending operation is disabled until it is received, sending to the email destination is prohibited, and when a reply email indicating permission to send the email is received, the email sending operation is enabled. And a function as an e-mail transmission means for transmitting the e-mail.

  Therefore, when an e-mail attached with a transmission file is transmitted as a business, the transmission file is temporarily stored in the transmission destination (customer) of the transmission file storage device 2 or in a directory corresponding to the transmission destination and the type of transmission file. Or, by specifying the destination and the type of file to be sent, it will be attached to the email sent to the destination, so at least when you attach the send file to the email, you will prevent mistaken operations to attach different send files can do.

Also, by specifying the destination or destination and the type of file to be sent, the destination email address is automatically entered, so when entering the email address, the wrong operation of entering a different email address is prevented. be able to.
In addition, an e-mail that is created and attached with a transmission file cannot be transmitted only by the operator's operation and needs to be checked by the general operator. Therefore, erroneous transmission of the transmission file can be prevented more reliably. Can do.

The business processing system 1 generates a transmission file for each transmission destination, and associates the transmission destination or the transmission destination and the type of transmission file with the directory in which the transmission file of the transmission file storage device 2 is stored. Based on the directory information, it functions as a transmission file generation device that stores the generated transmission file in a directory of the transmission file storage device corresponding to the transmission destination or the like.
Therefore, when the transmission file is stored in the transmission file storage device 2, it is automatically stored in the transmission destination or the directory corresponding to the transmission destination and the type of the transmission file by the business processing system 1 as the transmission file generation device. When the transmission file is temporarily stored in the transmission file storage device, it is possible to prevent an erroneous operation of storing different transmission files by mistake in the transmission destination or the directory corresponding to the transmission destination and the transmission file.

  When the transmission file is automatically stored in the transmission file storage device 2, for example, even if the contents of the transmission file are manually input, the transmission destination or transmission destination of the transmission file storage device 2 and the transmission file are temporarily stored. Since the transmission file is stored in the directory corresponding to the type of the file, there is no possibility that the transmission file is mistaken unless the transmission file is moved to a different directory.

  In addition, the mail transmission device can change the mail address of the e-mail to be transmitted and send it without providing the function of changing the e-mail address of the e-mail to be created and changing the attached transmission file. Since changing the file is prohibited, the operator who sends the e-mail, after performing the operation to specify the destination or destination and the type of the file to be sent, automatically determines the mail address and the file to be sent. Therefore, it is possible to prevent the erroneous operation of the operator more reliably.

  In addition, the access restriction is given to the transmission file by the above-mentioned password, and if the password is not set in the transmission file attached to the e-mail, it becomes impossible to send the e-mail. ing.

That is, as an access restriction determination means for determining whether or not a password is applied as a restriction for prohibiting a third party different from the transmission destination from opening the transmission file by encryption or the like in the mail transmission device. And a function as electronic mail transmission prohibiting means for prohibiting transmission of an electronic mail when it is determined that the restriction is not applied to a transmission file attached to the created electronic mail.
Therefore, even if the transmission file is erroneously transmitted, the transmission file cannot be opened at the erroneous transmission destination, and data leakage can be prevented.

Further, when an e-mail attached with a transmission file is transmitted, the transmission file is moved from the directory stored before the transmission to the transmitted directory.
That is, the transmission file storage device 2 is provided with a directory for storing transmission files that have been transmitted, and the mail transmission device stores the transmission file attached to the e-mail transmitted by the e-mail transmission means. The apparatus 2 functions as transmission file moving means for moving from the directory in which the transmission file before transmission is stored to the directory in which the transmission file already transmitted is stored.
Therefore, since the transmission file once transmitted does not exist in the directory corresponding to the transmission destination or the transmission destination and the type of the transmission file, it is possible to prevent the transmission file from being transmitted twice by mistake. If retransmission is necessary, the transmission file in the transmitted directory may be moved to the directory before transmission.

  In addition, the business processing system 1 can generate a plurality of types of transmission files for each transmission destination, and when generating the transmission file, information indicating the transmission destination and the type of transmission file in the generated transmission file And the mail transmission device stores the transmission file having the file name corresponding to at least a part of the transmission file name described above, stored in the directory corresponding to the transmission destination and the type of transmission file of the transmission file storage device 2. Since it is attached to the created e-mail, the transmission file can be accurately selected even if other files are mixed in the directory corresponding to the transmission destination of the transmission file storage device 2 and the type of the transmission file.

  In addition, the mail transmission device functions as a text storage unit that stores a fixed text that is the text of the email corresponding to the transmission destination and type of the transmission file, and determines the transmission destination and type of the input transmission file. Since the fixed text selected corresponding to the text is used as the text, it is possible to easily create an e-mail and to prevent an error in the text. That is, for example, when a daily report is transmitted by business e-mail, the body text may be the same every time, so that it is possible to easily create an e-mail by automatically inputting it.

In addition, as described above, a plurality of standard sentences may be facilitated for a combination of one transmission destination and a transmission file type, and an appropriate standard sentence may be selected from among them. In this case, for example, when the above error report file is used as a transmission file, there are cases where an error has occurred and no error has occurred. If no error has occurred, the error history and error There is no need to see an error report file that is a history of correspondence, and there is no need to attach an error report file as a transmission file.
In such a case, it is possible to reliably store useless files by storing those with and without errors as fixed phrases, and not sending files when a fixed sentence without errors is selected. Can be eliminated.

In other words, the mail transmitting device as the text storage means stores a plurality of types of fixed texts as the text of the electronic mail corresponding to the transmission destination of the transmission file and the type of the transmission file, and stores them in the text storage means. The types of standard sentences to be included include those that become the body of an e-mail that does not require an attached file, and the e-mail transmission device as the e-mail creation unit includes the transmission destination and the transmission input by the transmission destination input unit A plurality of types of fixed texts that are e-mail texts corresponding to file types are read from the text storage means.
Further, the e-mail transmission device functions as a selection unit that enables an operation of selecting one fixed phrase from a plurality of types of fixed phrases read by the e-mail creating unit. An e-mail transmission device as an e-mail transmission means transmits an e-mail without attaching a transmission file when an operation for selecting a fixed sentence that is a body of the e-mail is performed. .

In addition, in the mail check terminal 5 as a mail check device, when a confirmation e-mail attached with an e-mail to be transmitted is received, the confirmation e-mail has approval and non-approval buttons, and one of these buttons is operated. By doing so, an approval or non-approval reply mail can be transmitted to the mail transmission device, and the operability is excellent.
That is, when a mail transmission device as a mail confirmation means transmits an email created to a mail check device, the created email is attached to a confirmation email with the mail check device as a transmission destination, and confirmed. The e-mail for use is provided with selection operation means (approval button, non-approval button) for selecting whether or not transmission of the created e-mail is permitted, and the e-mail check device is selected by the selection operation means. Based on the above, a reply mail transmitting means for transmitting a reply mail indicating whether the mail transmission apparatus is permitted (approved) or not (not approved) is provided.

Note that the present invention is not limited to the above-described embodiment. For example, the mail generation device does not have to be the business processing system 1 as described above, and at least the transmission destination or the transmission destination and the type of transmission file are used. A corresponding transmission file may be created and the created transmission file may be stored in the transmission file storage device as described above.
Further, assuming that there is no mail generation device, a transmission file may be created based on the operation of the operator and stored in the transmission file storage device as described above.
That is, it is sufficient that the transmission file is stored in a directory corresponding to the transmission destination of the transmission file storage device 2 or the transmission destination and the type of transmission file.
