Abstract

PURPOSE:To use effectively the memory device of the called side terminal by returning the electronic mail, in which the stipulated data expired, to the sending side. CONSTITUTION:When an electronic mail terminal 101 receives an electronic mail from a transmission line 200, an electronic mail main body and a sending side terminal information are preserved at a memory device 500, and the time information is sent to a date supervising circuit 600. When the removing request of the electronic mail is executed from a mail input output device 700, a central control device 800 indicates the supervising stop to the date supervising circuit 600 and removes the electronic mail from the memory device 500 and executes the output. When the removing request of the electronic mail is not executed and the date supervising circuit 600 is time-outed, the central control unit 800 removes the electronic mail main body and the sending side terminal information from the memory device 500, returns the electronic mail main body from the sending side terminal information through a transmitting control circuit 300 to a sending side terminal 100, and deletes the information of the electronic mail main body from the memory device 500.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mail processing method for an electronic mail system.

BACKGROUND OF THE INVENTION Conventionally, in e-mail systems, there has been a service called certified mail in order to check whether an e-mail sent by oneself has been delivered to the called party and has been retrieved. With this service, when the called party retrieves the e-mail,
This is to notify the calling party that the mail has been retrieved.

Problems to be Solved by the Invention However, with the above-mentioned conventional certified mail service, if the mail is not retrieved, it is stored in the terminal's storage device and cannot be used to receive other mail. The disadvantage was that it was not possible. This drawback is particularly noticeable when multiple people share the device.

The present invention has been made in view of the above-mentioned conventional circumstances, and
Therefore, an object of the present invention is to provide a new method that eliminates the above-mentioned drawbacks and makes it possible to effectively utilize the storage device of a terminal by sending e-mails that have passed a predetermined number of days back to the sending terminal. The purpose of this invention is to provide a method for processing e-mails.

Means for Solving the Problems In order to achieve the above object, the e-mail processing power type according to the present invention includes a means for adding a response and a delivery time to the originating terminal in the e-mail body. , means for monitoring whether the delivered e-mail has been retrieved,
When sending an e-mail from the calling terminal 4, the e-mail body is given the address and delivery time of the calling terminal 111, and the e-mail body is stored in the storage device of the called terminal, and the called terminal The e-mail is monitored to see if it is retrieved, and if the e-mail is not retrieved within a predetermined number of days, the e-mail is sent back to the originating terminal.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing an example of an e-mail system related to misfires, and FIG. 2 is a block diagram showing an example of the configuration of each e-mail terminal.

In FIG. 1, the e-mail system is made up of e-mail terminals 100, 101 and 102, and a communication route 200. In the t42 decoy, the e-mail terminal 100 includes a transmission path control circuit 300 and an address time assigning circuit 400.
, a memory table @500, a days monitoring circuit 600, a mail input/output device fi700, and a central control unit 800.The transmission path control circuit 300 is connected to the transmission contract ω in FIG. E-mail terminals 101 and 102 are also configured similarly to e-mail terminal 100.

Next, the operation of this embodiment will be explained using FIGS. 1 and 2.

When sending an e-mail from the e-mail terminal 100 to the e-mail terminal 101, the e-mail input/output device t70
If you enter the e-mail body and the called terminal 101 from 0,
The central control device 800 sends the e-mail body to the address and time assigning circuit 400. At the same time, called terminal information 101
is sent to the transmission control circuit 300.

The address and time adding circuit 400 adds the address and delivery time of its own terminal 100 to the e-mail body and sends it to the transmission path control circuit 300. The transmission control circuit 300 sends this e-mail to the transmission path 200 by specifying the e-mail terminal 101 as the destination. The e-mail terminal IO1 is connected to the transmission line 20
When receiving or receiving an e-mail from 0, the e-mail body and sender terminal information are stored in the storage device 11500, and time information is sent to the number of days monitoring circuit 600.

The number of days monitoring circuit 600 starts comparing the number of days with a predetermined number of days. Mail input/output device i! When there is a request to retrieve e-mail from 700, the central controller 600 instructs the number of days monitoring circuit 600 to stop monitoring, and stores the memory table @5.
Extract the e-mail from 00 and output it.

There is no e-mail retrieval request, and the number of days monitoring circuit 600
If timeout occurs, the central control unit m soo
extracts the e-mail body and the originating terminal information from the memory table @500, and uses the originating terminal information from the transmission control circuit 300.
The e-mail body is returned to the originating terminal 101 through the sender terminal 101, and the information of the e-mail body is deleted from the storage table rIt500.

As described in detail, according to the present invention, by returning e-mails that have passed a predetermined number of days to the sender, it is possible to make effective use of the storage device of the called terminal.

[Brief explanation of drawings]

FIG. 1 is a block diagram showing an embodiment of an e-mail system according to the present invention, and FIG. 2 is a block diagram showing an example of the configuration of the e-mail terminal shown in FIG. 1.

Claims (1)

[Claims] In an e-mail system in which the terminal has an e-mail sending/retrieval function and a storage device for storing e-mail, a means for adding the sender terminal's address and delivery time to the e-mail body. and a means for monitoring whether the delivered e-mail has been retrieved, and when the e-mail is sent from the sending terminal, the e-mail body is given the address of the sending terminal and the delivery time, and the e-mail is sent.
