Is a mail sending means, 12 is a mail receiving means, and 13 is a mail holding means. Although not shown, the computers 2 and 3 also have a mail transmitting means 11, a mail receiving means 12, and a mail holding means 13 like the computer 1. When sending a mail from the computer 1 to the other computers 2 and 3 on the network 5, the mail is sent to the mail server 4 by the mail sending means 11 and temporarily held in the mailbox therein. The destination computer 2 or 3 checks the mailbox of the mail server 4 by the mail receiving means, and if there is a mail addressed to itself, extracts it and stores it in the mail holding means. Then, if necessary, the mail is read from the mail holding means and the contents thereof are displayed.

By the way, when a mail is mistakenly sent, it may be necessary to cancel or correct it after sending the mail. As described above, when canceling a once-transmitted mail, the conventional mail sending / receiving device sends a mail cancel command to the mail server 4 to cancel the mail held in the mailbox of the mail server 4. Further, when correcting a once-transmitted mail, a mail cancel command is sent to the mail server 4 to cancel the mail, and then the corrected mail is retransmitted.

As a conventional document relating to such a mail transmitting / receiving device, for example, Japanese Patent Laid-Open No. 3-2355 is known.
There is No. 52 publication.

[0005]

However, in the above-mentioned conventional technique, it is possible to cancel or correct the transmitted mail by the mail server 4.
However, there is a problem that it becomes impossible after the destination computer retrieves the mail from the mail server 4 only while it is inside. Further, when it is desired to correct, it is necessary to send a cancel command once and then send a correction mail again, which is troublesome. An object of the present invention is to solve such a problem.

[0006]

In order to solve the above problems, in the mail transmitting / receiving apparatus of the present invention, one of the new mail transmission mode, the cancellation mail transmission mode and the correction mail transmission mode is set as the transmission mode. Mode setting means, mail sending means for sending the mail by adding the mail identification code and the sending mode set by the mode setting means, mail holding means for holding received new mail and modified mail, and received mail And a mail deleting means for deleting the mail having the same identification code as the identification code added to the mail from the mail holding means when the received mail is a cancel mail or a correction mail. When the received mail is a new mail or a modified mail, It was that it comprises a mail storage means for storing the lifting means.

[0007]

[Operation] When sending a mail, the mode setting means sets one of the new mail send mode, the cancel mail send mode, and the modified mail send mode.
The mail sending means adds the mail identification code and the sending mode set by the mode setting means to the mail and sends the mail. On the other hand, when receiving mail, the mode determination means
The transmission mode of the received mail is determined, and if the mail is a new mail, the mail storing means stores the new mail in the mail holding means. If the received mail is a cancel mail, the mail deleting unit deletes the mail having the identification code added to the cancel mail from the mail holding unit. If the received mail is a correction mail, the mail deleting unit deletes the mail having the identification code added to the correction mail from the mail holding unit, and the mail storing unit deletes the correction mail. The mail holding means holds it.

In this way, since the mail cancellation request or correction request is transmitted as a mail, it is possible to cancel or correct the target mail in the received terminal computer without involving the mail server. Become. Therefore, the mail can be canceled or corrected even after the destination computer retrieves the mail from the mail server. Further, when making corrections, it is possible to correct the mails by sending only one correction mail, and therefore it does not take time and effort.
