If it is found that there is no e-mail transmission, the mail can be deleted or a destination determined to be a non-delivery destination can be newly registered.

Next, a second embodiment of the present invention will be described with reference to FIG.
Explanation will be made based on

In the second embodiment, the user operates the operating means 1
7 refers to a non-recipient address registered in the non-recipient address storage means 17, when a certain non-recipient address is an old destination that is not currently used, and when a new destination to replace it is known. The destination can be described together with the old destination.

As in the first embodiment, when sending a certain e-mail (hereinafter referred to as e-mail A) to the outside, the non-delivery destination search means 13 transmits all e-mails specified by the e-mail A. Extraction of the destination. Next, the non-delivery destination search means 13 reads out all non-delivery destinations stored in the non-delivery destination storage means 14. Next, the non-delivery destination search means 13 compares the destination of the electronic mail A with the non-delivery destination read from the non-delivery destination storage means 14 in order from the first destination if there are a plurality of destinations.

At this time, if the destination specified in the electronic mail A matches the destination of the non-delivery destination, the destination of the electronic mail A is a destination that has not been previously reached. Further, the unreachable destination search means 13 confirms whether the designation of a new destination to replace the unreachable destination is defined in the unreachable destination storage means 14. If a new destination is specified, the new destination replaces the destination that the electronic mail may not reach. If all the non-delivery destinations of the electronic mail can be replaced with the new destinations, the transmission of the electronic mail is performed without notifying the display means 16 of the non-delivery destination.

Further, for each unreachable destination in the unreachable destination storage means 14, the number of times the unreachable destination was used when sending the e-mail, the date and time of last use, and the case where a new destination is specified. It is also possible to provide history information such as the number of times it has been used to the non-delivery destination search means or the like.

The first effect is that when a user attempts to send a single e-mail and there is a destination of the e-mail which has not been previously received, the non-delivery destination is set. Search and display. As a result, when a user attempts to send a single e-mail, the user does not rely on the user's memory as to whether any of the e-mail destinations was previously unsuccessful. Retransmission to another destination can be prevented.

The reason is that the non-reachable destination of the undelivered e-mail is automatically extracted and stored, and the unreachable destination is retrieved when the user tries to send one e-mail. This is because it can be displayed.

The second effect is that a new destination that can be transmitted is replaced with a non-delivery destination that has collected and stored past non-delivery destinations from the user. If there is a destination and a new destination corresponding to the non-delivery destination is specified, it will be automatically replaced with the new destination and the transmission will be performed, so there is no need to receive an e-mail for non-delivery notification, which will help to improve efficiency become.
