<< Mail archive processing >>
Next, processing performed in the mail archive system 1 will be described.
FIG. 8 is a flowchart illustrating an example of a process performed by the mail archive system 1 to archive the original mail 200 received by the mail system 101 (hereinafter, referred to as a mail archive process). This process is started, for example, when the mail system 101 and the mail processing server 104 are activated.

  First, the mail system 101 waits for reception of an original mail 200 from an external information processing device (s301). Upon receiving the original mail 200, the mail system 101 creates an archive mail 250 from the received original mail 200, and transmits the created archive mail 250 to the mail archive data processing system 111 (s302).

  Specifically, for example, upon receiving the original mail 200, the mail server 102 transfers the original mail 200 to the archive delivery MTA server 103. The archive delivery MTA server 103 generates an archive mail 250 in which the original mail 200 is used as the main body 203 and the archive address of the group company specified from the original mail 200 and the like is attached as the envelope information 201. 250 is transmitted to the mail archive data processing system 111.

Note that reference numeral 501 in FIG. 9 shows an example of the generated archive mail 250. In the envelope information, “arc@a.co.jp”, which is the RcptTo item, is set as an archive address.

  Next, as shown in s402 of FIG. 8, upon receiving the archive mail 250, the mail archive data processing system 111 acquires the mail addresses of the transmission source and the transmission destination from the received archive mail 250. Specifically, for example, the mail processing server 104 uses the envelope information 205 included in the main body 203 of the archive mail 250 to read the source and destination mail addresses (for example, the Sender section, To section, Cc section, and Bcc section). ) To get.

  The mail archive data processing system 111 determines whether the acquired destination address is included in the registered destination address (s403). Specifically, for example, the mail processing server 104 determines whether or not the transmission destination address is registered in any record of the archiving target mail address column 301 of the archiving target user information DB 106. If there are a plurality of destination addresses acquired in s402, it is determined whether any of the plurality of destination addresses is registered in the archive subject email address column 301, and if any of them is registered, It is determined that the destination address is included in the registered destination address.

  When the transmission destination address is not included in the registered transmission destination address (s403: NO), the mail archive data processing system 111 discards the archive mail 250 (s407), and ends the mail archive processing (s409).

On the other hand, when the destination address is included in the registered destination address (s403: YES), the mail archive data processing system 111 acquires a list of registered archive addresses corresponding to the registered destination address (s404). Specifically, for example, the mail processing server 104 acquires all the contents of the archive address column 302 of the record of the archive target user information DB 106 whose transmission destination address is registered in the archive target person email address column 301. When there are a plurality of destination addresses, a record is acquired for each of the plurality of destination addresses.

  The mail archive data processing system 111 determines whether the archive address indicated by the envelope information 201 of the archive mail 250 is registered in the list of registered archive addresses acquired in s404 (s405). Specifically, for example, the mail processing server 104 determines whether or not the address of the RcptTo item in the envelope information 201 is registered in the list of registered archive addresses acquired in s404.

  If the archive address is not registered in the list of registered archive addresses (s405: NO), the mail archive data processing system 111 discards the archive mail 250 (s407), and ends the mail archive processing (s409).

  On the other hand, if the archive address is registered in the list of registered archive addresses (s405: YES), the mail archive data processing system 111 rewrites the source mail address in the envelope information 205 of the archive mail 250 with the archive address. Then, a modified mail is generated (s406). Specifically, for example, the mail processing server 104 changes (rewrites) the mail address of the MailFrom item or the RcptTo item of the envelope information 205 to the address of the RcptTo item of the envelope information 201. Whether to use the MailFrom item or the RcptTo item in the envelope information 205 is determined according to, for example, the specification of the mail archive execution system 112.

Note that reference numerals 502 and 503 in FIG. 9 show an example of the processing in s403 to s406. As indicated by reference numeral 502, the destination address indicated by the envelope information 205 of the archive mail 250 (“101@xxx.co.jp” in the To section, “202@yyy.co.jp” in the Cc section, and “202@yyy.co.jp” in the Cc section, and “ 102@xxx.co.jp)), “101@xxx.co.jp” and “102@xxx.co.jp” are registered in the archiving-subject email address column 301 of the archiving-target user information DB 106, Among the records of the archive target user information DB 106 in which these (“101@xxx.co.jp” and “102@xxx.co.jp”) are registered, the archive address column 302 of the record in which the latter is registered The archive address "arc@a.co.jp" is registered (S40 in FIG. 8).
3-S405. ). Therefore, as indicated by reference numeral 503, the Sender section “102@xxx.co.jp” of the envelope information 205 is changed to the RcptTo section (“arc@a.co.jp”) of the envelope information 201 (FIG. 8). S406).

  Next, as shown in s408 of FIG. 8, the mail archive data processing system 111 transmits the processed mail generated in s406 to the mail archive execution system 112 (s408).

  Upon receiving the processed mail, the mail archive execution system 112 archives the original mail 200 expanded from the processed data based on the specifications of the archive system (s501, s502).

  Specifically, for example, the mail archive server 108 expands the text 203 as the original mail 200 based on the envelope information 201 of the processed mail (the envelope information newly attached in s302) (s501). Then, the mail archive server 108 stores the original mail 200 in the tenant area 110 associated with the domain of the address (archive address rewritten in s406) indicated by the envelope information 205 attached to the expanded original mail 200. (S502).

Note that reference numerals 504 and 505 in FIG. 9 show an example of the processing in s501 to s502 in FIG. The main body 203 of the modified mail in which the Sender section of the envelope information 205 is rewritten to “arc@a.co.jp” is expanded as the original mail 200 (reference numeral 504), and the envelope information of the expanded main body 203 (the original mail 200) The original mail 200 based on the body text 203 is stored in the tenant area 110 of “group company A” which is a group company associated with “@ a.co.jp” which is the domain indicated by 205 (reference numeral 506). At this time, the envelope information of the original mail 200 is converted into the original format by rewriting the Sender term of the extracted text 203 into the MailFrom term and rewriting the To, Cc, and Bcc terms of the text 203 into the RcptTo term. return.

  As described above, the mail archive system 1 of the present embodiment acquires the archive mail 250 with the archive address attached to the original mail 200 as new envelope information, and the archive mail 250 is registered in the archive target user information DB 106. In this case, a modified mail in which an archive address is set in the envelope information of the original mail 200 in the archive mail 250 is generated.

  That is, the mail archive system 1 of the present embodiment generates a processed mail in which the archive address is set in the envelope information of the original mail 200 in the archive mail 250 so as to be compatible with the specification of the mail archive execution system 112. The mail archive execution system 112 can archive the original mail 200 received by the mail server 102 in an appropriate tenant area 110 according to the archive address. As described above, according to the mail archive system 1 of the present embodiment, the acquired mail can be appropriately archived according to the contents.

  For example, archiving for each tenant or each user is possible without depending on the mail domain of the transmission destination of the original mail 200. For example, even when the mail system 101 receives mail of a common domain in a plurality of group companies, it is possible to archive for each tenant or user in each group company. Even in an organization where the mail address of the original mail 200 is managed in the same mail domain, each mail can be archived in smaller organizational units (for example, in units of departments or users).

[Second embodiment]
In the mail archive system 1 of the first embodiment, the mail archive data processing system 111 performs archiving based on the information of the mail address of the destination of the archive mail 250 (information of the destination of the original mail 200), and To determine the archive destination, in the mail archive system 1 of the second embodiment, the mail archive data processing system 111 uses the information of the mail address of the sender of the archive mail 250 (information of the sender of the original mail 200). Whether to perform archiving and the destination of archiving are determined based on. Hereinafter, differences from the first embodiment will be described.
