To receive. In this case, it is assumed that the print e-mails having the mail identifiers a and b are received.

In this case, the mail delivery unit 112 activates the print control device 114 by, for example, a "CALL command" or the like, and the print information stored in the content P2 of the print electronic mail is sent to the print control device 114. And send the e-mail identifier set in the envelope P1,
A printout of the print information is requested.

Upon receipt of the request, the print control device 114 transmits the print information to the printing device 120 and controls the print output of the printing device 120. Under the control, the printing device 120 actually prints out the print information (print data) on paper. In this case, the print output may fail due to a malfunction of the printer engine.

The printing apparatus 120 prints the operation result (information indicating success or failure) of the print output as described above.
Return to. Upon receiving the operation result from the printing device 120, the print control device 114 associates the result of the printing process with the mail identifier of the electronic mail that is the target of the printing process, and sets the execution date and time of the printing process. Created record and write the record to the intermediate file 130.

By the above operation, the intermediate file 1
The print result of the print e-mail with the mail identifier a and the print result of the print e-mail with the mail identifier b are sequentially written in 30. In the example shown in the figure, a record (record a) indicating that the print output of the print email of the mail identifier a has succeeded and a record (record a) indicating that the print output of the print email of the mail identifier b has failed ( Record b)
Is schematically shown.

The print result analysis unit 116 uses the intermediate file 1
The contents of 30 are monitored at regular time intervals, and the intermediate file 1
The record a and the record b are read from 30.
Then, with reference to the print result information in the records a and b, the delivery notification is created for the electronic mail having the mail identifier a, and the non-delivery notification is created for the electronic mail having the mail identifier b. Then, these notifications are transmitted to the mail delivery unit 112. At the time of delivery / non-delivery notification, the "original sender's address" and the "original recipient's address" are set in the envelope P1 '. Acquisition of these addresses is set in the read record. It is carried out based on the "mail identifier" that has been set. The management information of the "mail identifier" and the corresponding "sender address (original sender address)" and "recipient address (original recipient address)" is created by the mail delivery unit 112 when receiving an e-mail, for example. Then, the print result analysis unit 116 (not shown) stores it in the accessible memory.

When the mail delivery unit 112 receives these delivery notification and non-delivery notification, the mail identifier a,
The sender of the print e-mail having the mail identifier b is notified (returned).

Subsequently, the host system 100 having the above configuration

When the printing output is completed, the printing apparatus 120 returns an operation result indicating whether the printing has succeeded or failed to the printing control apparatus 114 by a status signal or the like. When the print control device 120 receives the operation result (print process result), the print control device 120 creates a record in which the result is associated with the stored mail identifier, and the print process execution date and time is set. Then, this is written in the intermediate file 130 (S24). Then, step S21
Return to.

Next, FIG. 7 is a flow chart for explaining the operation of the print result analysis section 116 in detail. The print result analysis unit 116 monitors the contents of the intermediate file 130 at regular time intervals, and if the record written by the print control device 114 in step S24 of FIG. 6 described above exists in the intermediate file 130. , The record is read, for example, in time series (in the order of written time), and the mail identifier and the print result are taken out from the record (S3).
1).

Then, the contents of the print result information are examined to determine whether or not the print processing of the print e-mail having the mail identifier has been successful (S32). If it is determined that the print processing is successful by the determination, based on the mail identifier and the print result information by the method described above,
A delivery notification of the format shown in (b) is created, and this notification is sent to the mail delivery unit 112 (S33). On the other hand, if it is determined that the print processing has failed from the above determination,
Based on the mail identifier and the print result information, a non-delivery notification of the format shown in FIG. 3 (b) is created by the method described above, and this notification is transmitted to the mail delivery unit 112 (S3).
4).

The above step S33 or step S34
After performing the processing of (3), it is determined whether or not the last record stored in the intermediate file 130 has been extracted (S3
5) If there is a record that has not been taken out yet, the process returns to step S31.

As described above, steps S31 to S3
When the process of No. 4 is performed on all the records stored in the intermediate file 130, after waiting for a certain period of time (S36), the process returns to step S31.

In this way, the print result analysis unit 116 monitors the contents of the intermediate file 130 at regular time intervals, creates delivery notifications or non-delivery notifications for print e-mails, and sends these notifications to the mail delivery unit 112. Send to.

Next, FIG. 8 shows step S of FIG.
15 is a flowchart illustrating a detailed operation of a normal email process of 15. In this process, first, it is determined whether or not the destination (recipient address of the envelope P1) designated by a normal electronic mail actually exists in the own system. This determination is made by referring to the "address management ledger" which is a resource of the mail service prepared in the own system. This "address management ledger" stores all destination information in the own system (S151).
If the destination actually exists (S151, YES), the electronic mail is stored in the mailbox of the destination (not shown) (S152).

Next, it is judged whether or not the storage is normally performed (S153), and if it is normal (S153, YES),
A delivery notification in the format shown in FIG. 3B is created, and the sender is notified (returned) via the mail network 70 (S154).

On the other hand, if the storage in the mailbox is not normally performed in the above step S153, FIG.
A non-delivery notification of the format shown in (1) is created, and this is notified (returned) to the sender of the electronic mail via the mail network 70 (S155).

In step S151, if the destination designated by the e-mail does not exist in the own system (S151, NO), the process of step S155 is performed and the non-delivery notification is sent to the mail network 70. Notify (return) to the sender of the above email via
