  Next, transfer mail control processing will be described with reference to the flowcharts shown in FIGS.

  In step S101, when the user operation unit 300 receives an instruction for setting to automatically transfer an e-mail received from a screen (not shown), the mail transmitting / receiving apparatus 102 registers the setting in itself.

  This setting is assumed to be set for each user, for example, and various conditions for forwarding are set according to the mail address of the destination of the received mail. The description for applying the existing technology from is omitted.

  In step S102, the mail transmission / reception unit 302 receives an e-mail from the other company's system, which is an external system, via the Internet and the mail relay device 103. In step S103, the conditions for performing the transfer set in step S101 are satisfied. The received electronic mail is transferred to the mail relay apparatus 103.

  In step S104, the relay mail transmission / reception means 307 receives the electronic mail transferred in step S103, and in step S105, the forward mail determination means 308 determines whether the function for determining whether the forward mail can be transferred is ON or OFF. If it is determined to be ON, the process proceeds to step S106. If it is determined to be OFF, the process proceeds to step S124.

  In step S106, the forwarded mail determination unit 308 determines whether or not the email received in step S103 is transmitted from the mail transmission / reception device 102, and determines that it is transmitted from the mail transmission / reception device 102. If the process proceeds to step S107 and it is not determined that the mail has been transmitted from the mail transmitting / receiving apparatus 102, the process proceeds to step S124.

  In step S107, the forwarded mail determination unit 308 determines whether the email received in step S103 is a forwarded mail based on the information stored in the forwarded mail format information table, and determines that the forwarded mail is a forwarded mail. If YES in step S108, the process advances to step S108. If it is not determined that the mail is a forwarded mail, the process advances to step S124.

  In this determination, for example, the received email mailer product is FortMail, the value of the Receive header of the email has an external domain address, the value of the X-Forward-To / For header, and the value of Auto- If the value of the Submitted header is auto-forwarded, it is determined that the e-mail is a transfer mail. Since the e-mail format differs depending on the product, it is possible to make a determination in consideration of this difference.

  In step S108, the forwarded mail determination unit 308 determines whether or not the email received in step S103 is addressed to the outside based on the information stored in the external address information table, and determines that it is addressed externally. If so, the process proceeds to step S109. If it is not determined that the address is external, the process proceeds to step S124.

  For example, when the mailer product of the received e-mail is FortMail and the value of the X-Forward-To header is set to the mail address of the external domain, this determination is made to be addressed externally.

  In step S109, the forward mail determination unit 308 determines whether the set forward mail level (value set in the determination level 602) is high or low. If it is determined that the level is high, the process proceeds to step S110. If it is determined that the value is low, the process proceeds to step S112.

  In step S110, the forwarding mail determination means 308 is based on the information stored in the forwarding destination confirmation information table in order to confirm whether the electronic mail received in step S103 is a forwarding mail created automatically.

According to, for example, in condition 4, the value of the Auto-Submitted header is “auto-forward”, which indicates that the e-mail is automatically transferred.

  However, depending on the type of mailer, it may be difficult to specify such information from the format. Furthermore, in other mail systems, it is easy to understand and does not always add a header. It is difficult to determine whether it was done.

  Therefore, when determining whether or not an electronic mail has been automatically transferred, it can be determined more reliably by setting high at the determination level 602.

  As a method of this confirmation, for example, when the product of the received e-mail mailer is FortMail, the e-mail is transmitted with the e-mail address of the value set in the X-Forward-For header as the transmission destination. An example of the format of the e-mail to be sent is shown in FIG.

  In this e-mail, a fixed address (system_forward @ <SERVERQDN>) that identifies the mail relay apparatus 103 is set as a sender address for From :, and whether or not the e-mail is an automatically created forward mail. Is set to X-Forward-Mail-Check: to indicate that it is an e-mail for confirming.

  In addition, the body of the electronic mail is also set to indicate that it is a forwarded mail created automatically. For example, the contents below “transfer confirmation mail” are set.

  In step S111, the forwarded mail determination unit 308 determines whether or not the electronic mail transmitted to the mail transmitting / receiving apparatus 102 in step S110 is forwarded. If it is determined that the forwarded mail has been forwarded, the process proceeds to step S112. If it is determined that the data has not been transferred, the process proceeds to step S124. Normally, it is assumed that an e-mail is transferred when a few seconds have passed. Therefore, if the e-mail is not transferred within a predetermined time set in advance, it may be determined that the e-mail is not transferred. .

  In step S112, the forwarded mail determination unit 308 determines whether the operation for the email received in step S103 is deletion or quarantine. If it is determined to be deletion, the email is deleted and processed. If the e-mail is determined to be quarantined, the e-mail is stored in the quarantine e-mail storage means 310, and in step S113, an e-mail for notifying that the e-mail is quarantined to the set administrator e-mail address Is transmitted to the administrator terminal device 101 by the relay mail transmission / reception means 307.

  In step S114, the notification mail transmitted in step S113 is received by the management transmission / reception means 306. In step S115, when the management operation means 305 supports the display of the quarantine mail screen 1100, the quarantine mail screen 1100 is displayed. Is done.

  In step S116, the management transmission / reception unit 306 transmits information to the effect that the quarantine mail screen 1100 is displayed to the mail relay device 103. When the relay mail transmission / reception unit 307 receives the information, the management transmission / reception unit 306 stores the information in the quarantine mail storage unit 310. Information on the electronic mail is acquired and transmitted to the administrator terminal device 101.

  In step S117, the management operation unit 305 displays a list of information on the email transmitted in step S116 on the quarantined email list display unit 1101.

  In step S118, the management operation unit 305 displays the record selected by the administrator among the records displayed in the quarantine email list display unit 1101 on the quarantine email detail screen 1200, and then presses the delete button 1203. If it is determined, the process proceeds to step S119. If it is determined that the send button 1202 is pressed, the process proceeds to step S122.

  In step S119, the management transmission / reception unit 306 transmits information instructing deletion of the electronic mail displayed on the quarantine mail detail screen 1200 in step S118 to the mail relay device 103. In step S120, the relay mail transmission / reception unit 307 Information for instructing deletion of the electronic mail transmitted in step S119 is received.

  In step S121, the quarantine mail management processing unit 312 deletes the email to be deleted received in step S120 from the quarantine mail storage unit 310.

  In step S122, the management transmission / reception unit 306 transmits information instructing transmission of the e-mail displayed on the quarantine mail detail screen 1200 in step S118 to the mail relay device 103. In step S123, the relay mail transmission / reception unit 307 Information for instructing transmission of the e-mail transmitted in step S122 is received.
