  Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings. First, the first embodiment will be described.

[First Embodiment]
FIG. 1 shows a system configuration diagram of an electronic mail system 1 according to the first embodiment. As shown in FIG. 1, an electronic mail system 1 includes a mail delivery request device 2, a mail transmission server 4, a mail server 6, and a client device 8. Each device and server are mutually connected via a network 10 such as the Internet. Is communicably connected.

  The mail distribution request device 2 is a computer that requests the mail transmission server 4 to distribute an electronic mail addressed to the user's mail address. The mail delivery requesting apparatus 2 sets an expiration date, display data within the expiration date displayed within the expiration date, and display data outside the expiration date displayed after the expiration date has expired for the electronic mail to be distributed. In-expiration display data and out-of-expiration display data may include the subject, body, and other information that make up an email, or data that is common between in-expiration display data and out-of-expiration display data Alternatively, it may be determined as common data, or one data may be configured as difference data from the other data. The e-mail (delivery basic mail) including the expiration date, display data within the expiration date, and display data outside the expiration date may be sent to the mail transmission server 4 after being generated in the mail distribution requesting device 2, The mail transmission server 4 may generate the distribution basic mail by transmitting information on the expiration date, display data within the expiration date, and display data outside the expiration date to the mail transmission server 4.

  The mail transmission server 4 is a computer that transmits the electronic mail requested to be transmitted by the mail distribution requesting apparatus 2 to the mail server 6 that manages the mail address of the destination of the electronic mail. For example, when the mail transmission server 4 receives an e-mail distribution request from the mail distribution request device 2, the e-mail transmission server 4 registers the expiration date, display data within the expiration date, and display data outside the expiration date for the mail distribution request device 2. E-mail (delivery basic mail) to be transmitted based on each registered data may be generated.

  The mail server 6 receives and accumulates e-mail addressed to the user's e-mail address to be managed, and stores the e-mail accumulated when receiving a delivery request for e-mail sent from the client device 8 to the user's e-mail address. This is a computer that searches for a corresponding electronic mail from among the mails and distributes the searched electronic mail to the client device 8. In this embodiment, the mail server 6 transmits an email based on the display data within the expiration date if the expiration date set for the email (distribution basic email) received and accumulated from the email transmission server 4 has not expired. If the expiration date set for the delivery basic email has expired, an email based on the expiration date display data is delivered to the client device 8.

  The client device 8 is a computer operated by a user, and requests the mail server 6 to deliver an e-mail addressed to the user's mail address. The client device 8 may display the received electronic mail after receiving the electronic mail distributed from the mail server 6 in response to the electronic mail distribution request.

  Here, an example of the flow of processing performed in the electronic mail system 1 according to the first embodiment will be described with reference to the sequence diagram shown in FIG.

  As shown in FIG. 2, the mail transmission server 4 sends, for example, an e-mail destination, sender information, an e-mail expiration date, display data within the expiration date, display data outside the expiration date, etc. The electronic mail data is received (S1001), and a distribution basic mail is generated based on the electronic mail data (S1002). The mail transmission server 4 transmits the generated distribution basic mail to the mail server 6 that manages the destination electronic mail (S1003).

  FIG. 3 shows an example of the data structure of the distribution basic mail generated by the mail transmission server 4. In the example of the distribution basic mail shown in FIG. 3, the expiration date, the display data within the expiration date, and the display data outside the expiration date are described as HTML data. In the example shown in FIG. 3, the expiration date and the display data outside the expiration date are commented out, and the display data within the expiration date is not commented out, but the mode of the distribution basic mail is not limited to this. For example, it is possible to comment out both the display data within the expiration date and the display data outside the expiration date, and remove one of the comments depending on the expiration date, or write both without commenting out, depending on the expiration date. One of the data may be deleted. Further, the expiration date and the expiration date display data may be configured so that each data can be identified in a comment by surrounding the expiration date and outside expiration date display data with a predetermined tag.

  Returning to the sequence diagram of FIG. When receiving the distribution basic mail from the mail transmission server 4, the mail server 6 stores and manages the received distribution basic mail (S1004). The mail server 6 holds a mailbox for each registered user's mail address, and stores the received e-mail (including the distribution basic mail) in the mailbox corresponding to the e-mail address of the e-mail. It can be managed.

  When the mail server 6 receives a delivery request for an e-mail addressed to the user's mail address from the client device 8 (S1005), the mail server 6 reads out the distribution basic mail addressed to the user's mail address from the stored distribution basic mails ( S1006). Then, the mail server 6 determines whether or not the expiration date has expired for the read delivery basic mail based on the current date and time (S1007). If the mail server 6 determines that the expiration date has expired (S1007: Y), the mail server 6 displays based on the display data outside the expiration date instead of at least part of the display data within the expiration date included in the delivery basic mail. E-mail (that is, an expiration date display mail to be displayed outside the expiration date) is generated (S1008). In the example of this sequence, since the delivery basic mail is displayed based on the display data within the expiration date in the initial state, if it is determined that the expiration date has not expired (S1007: N), the distribution basis email The mail is used as it is as an e-mail for display (that is, a display mail within the expiration date that should be displayed within the expiration date) (S1009).

  The mail server 6 transmits an e-mail for display to the client device 8 (S1010), the client device 8 receives the e-mail transmitted from the mail server 6, and displays the received e-mail on a display means such as a display. (S1011). Here, if it is within the valid period, for example, the mail shown in FIG. 4A (displayed mail within the valid period), and if it is outside the valid period, for example, the mail shown in FIG. Will be displayed.

  In the example of the expiration date display mail shown in FIG. 4A, the campaign information is displayed based on the link A in the display column 100 because it is within the expiration date. On the other hand, in the example of the expiration date display mail shown in FIG. 4B, since the expiration date has expired, information indicating that the campaign information has ended based on the link B will be displayed in the display column 100. . Of course, the display mail within the expiration date and the display mail outside the expiration date are not limited to the illustrated example, and various display forms are realized according to the information replaced with the display mail within the expiration date in the display mail outside the expiration date. Needless to say. For example, the contents displayed in the expiration date display mail and the expiration date display mail may be partially common or may be completely different.

  The above is a series of processes performed in the electronic mail system 1 based on the sequence shown in FIG. Hereinafter, an example of functions provided in the mail transmission server 4, the mail server 6, and the client device 8 in order to realize the above-described processing will be described with reference to the functional block diagram shown in FIG.

For example, the expired mail search unit 68 acquires the current date and time, compares the acquired current date and time with the expiration date stored in the mail management table for the distribution basic mail acquired by the distribution target mail acquisition unit 66, It may be possible to search for a delivery basic mail that has expired.

  The display mail generation unit 70 sets at least a part of the display data within the expiration date for the distribution basic email searched by the expired email search unit 68 among the distribution basic emails acquired by the distribution target email acquisition unit 66. By replacing based on the external display data, an electronic mail for display (that is, for distribution distributed to the client device 8) is generated. For example, the display mail generation unit 70 may generate a display e-mail by uncommenting display data outside the expiration date, that is, by enabling display data outside the expiration date. Of course, the delivery mail generation processing is not limited to the above-described mode. For example, the display mail generation unit 70 validates out-of-expiration display data for the distribution basic mail searched by the expired mail search unit 68 among the distribution basic mails acquired by the distribution target mail acquisition unit 66, For other basic delivery mails (that is, delivery basic mails within the expiration date), display data may be generated by validating the display data within the expiration date. Further, the display mail generation unit 70 may generate a display mail of the following mode based on the distribution basic mail searched by the expired mail search unit 68.

  That is, the display mail generator 70 combines the information to be replaced based on the out-of-expiration display data included in the distribution basic mail searched by the expired mail search unit 68 into one e-mail (expired expiration notice mail). ) May be generated.

  FIG. 7 shows an example of an expiration date notification mail. As shown in FIG. 7, the expiration date notification mail displays a list of information on the distribution basic mails that have expired. For example, the information displayed includes the subject, sender, date and comment of each delivery basic email (this email has expired on XX days.
