When this duplicate notification is received, the sender of the e-mail is notified of this (s7).
The sender of the notified e-mail selects whether to keep the e-mail in the mail server 4 for forced reception or to discard it because it is duplicated (s8).

Here, when the sender designates forcibly receiving even duplicated e-mails, the maintenance notice is sent to the same mail processing unit 12 of the mail server 4.
(S9).

On the other hand, if the sender specifies that the e-mail is to be discarded due to duplication, a discard notification is sent to the same mail processing unit 12 of the mail server 4 (s10).

FIG. 3 is a flowchart showing processing executed by the same mail processing unit 12 of the electronic mail system according to the present embodiment. In the same mail processing unit 12 provided in the mail server 4, an electronic mail is first input (t1), and it is confirmed whether or not the mail type information indicates transfer (t2).

When the mail type information indicates transfer, the tracking information (the original mail ID and the original destination information) of the input electronic mail is confirmed (t3). Next, a list of each mail ID and destination information (a list indicating each mail and its delivery destination) stored in the mail database 11 is read (t4).

Next, the confirmed original mail ID and original destination information are compared with the read mail IDs and destination information (t5). It is determined that the destination is duplicated, and a duplicate notification indicating this is sent from the same mail processing unit 12 to the transmission unit 7.
(T6).

Then, a response to the transmitted duplicate notification is received (t7), and if this response is a discard notification,
This e-mail is discarded (t8), and the process is terminated. In the process, if the mail type information indicates new or reply, the original mail ID and the original destination information, each mail ID and the destination in the mail database 11, and If the information does not match, and if the response to the duplicate notification is maintained, the destination of the input e-mail is
(T9).

If a destination exists in the mail server 4, the mail ID and the destination information of the e-mail are stored in the mail database 11 (t 10) and sent to the delivery unit 13 provided in the same mail server 4. An e-mail is output (t11).

On the other hand, when the destination does not exist in the server 4, an e-mail is transmitted to the distribution unit of another server (t12). As described above, in the e-mail system according to the present embodiment, when the mail terminal 5 transfers an e-mail, the e-mail ID and the destination information of the e-mail that is the source of the transfer are transferred to the e-mail Include in. Further, when the mail server 4 receives the e-mail related to the transfer, the mail ID and the destination information of the e-mails received so far are compared with the original mail ID and the original destination information of the e-mail related to the transfer. I do. And
If the comparison results in a match, an inquiry is made to the sender as to whether the electronic mail relating to this transfer is to be discarded or maintained.

Therefore, in the present embodiment, when the transmitted e-mails are duplicated, the sender himself can instruct the discard of the e-mails. Can be prevented from being stored.

As a result, it is possible to improve the efficiency of the line usage fee when downloading to the mail terminal 5.
Further, it is possible to save time for referencing and organizing the received e-mail, and to improve the work efficiency of the e-mail recipient.

In the present embodiment, when creating a new e-mail or reply e-mail, the same values as the unique e-mail ID and destination information are applied as the original e-mail ID and original destination information, and the header is created. May be included. This makes it possible to examine the header of the e-mail and determine that the e-mail is not a forwarded e-mail if the unique e-mail ID and destination information match the original e-mail ID and the original destination information. As a result, even if the mail type information is omitted, the processing according to the present embodiment can be performed.

Similarly, flag information indicating that the electronic mail is not related to the transfer may be applied to the original mail ID and the original destination information of the electronic mail created in a mode other than the transfer mode.

Further, in the present embodiment, pointer information indicating the storage contents of the mail text attached file 10 is stored in the mailboxes 8a to 8c.
The e-mail itself is stored in the mailboxes 8a to 8c, and the mail body attachment file 10 may not be used.

Further, in the present embodiment, after selecting to create an electronic mail by forwarding or replying,
It is specified that the e-mail to be the source of this transfer and the e-mail to be returned are specified. Conversely, after specifying the read e-mail, the user can select to forward or reply to the specified e-mail. May be.

(Second Embodiment) In the first embodiment, the mail server prevents duplicate reception of the same mail.

On the other hand, in the present embodiment,
An e-mail system in which the mail terminal checks whether the same mail has been received twice before downloading the e-mail from the mail server and does not download unnecessary e-mails will be described.

In the present embodiment, an e-mail system will be described in which the contents of e-mail downloaded to the e-mail terminal are compared and only the difference of the selected e-mail is displayed to the recipient of the e-mail.

FIG. 4 is a block diagram showing the configuration of the electronic mail system according to the present embodiment. The same parts as those in FIG. 1 are denoted by the same reference numerals, and their description is omitted. Only will be described in detail.

The mail terminal 14 of this electronic mail system

FIG. 5 is a flowchart showing a process executed by the receiving section 16 of the electronic mail system according to the present embodiment. In the receiving unit 16, first, the mailbox assigned to the recipient is referred to, and only the header of the e-mail stored in the mailbox is downloaded (u1).

Next, the mail ID of the received electronic mail stored in the received mail storage unit 15 is read (u2). Next, the original mail ID of the downloaded header and the mail I
D is compared (u3).

As a result of the comparison, if the downloaded original mail ID matches the mail ID of the electronic mail in the received mail recording unit, the receiver is notified that the electronic mail is duplicated (u4).

Based on the notification, the receiver determines whether or not to download the electronic mail (u5). If it is determined that the download is not necessary, the process ends.

On the other hand, if it is determined that downloading is necessary, or if the downloaded original mail ID and the mail ID of the electronic mail in the received mail recording unit 15 do not match in the previous comparison, Is downloaded (u6), and the downloaded electronic mail is stored in the received mail storage unit 15 (u6).
7).

The above is a process for preventing the same electronic mail from being downloaded redundantly. In this process, if the recipient permits, even if the electronic mail has the same content, the electronic mail may be duplicated. Will be downloaded. A process in the case where there is a duplicate electronic mail after downloading by the recipient will be described below.

FIG. 6 is a flowchart showing processing executed by mail management unit 17 of the electronic mail system according to the present embodiment. In the mail management unit 17, first, a plurality of e-mails that may be duplicated are selected by the recipient from the received e-mails stored in the received e-mail storage unit 15 (v1). .

Next, the selected electronic mail is read from the received mail storage unit 15 (v2). As described above, when the selected e-mail is read, the duplication state notification function and the text difference display function for the e-mail are executed by the mail management unit 17 in parallel.

In the duplication status notification function, the original e-mail ID is compared between the selected e-mails (v3), and the duplication status of the selected e-mail is notified to the recipient (v4).
On the other hand, in the text difference display function, the text portion of the selected e-mail after the text is compared (v5), and the difference of the text portion after the text is notified to the receiver (v5).
