Abstract

PROBLEM TO BE SOLVED: To open e-mail without a waste of dealing time when we want to reread important mails and, this system effectively reduces the volume of data that will be preserved on a record medium. SOLUTION: Important e-mails' data is extracted following to a condition previously inputted. This e-mail data is preserved without compression and unimportant data is preserved with compression.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an e-mail system for transmitting and receiving e-mail, and more particularly to storage of e-mail transmitted and received at a terminal for transmitting and receiving e-mail.

[0002]

2. Description of the Related Art In recent years, transmission and reception of electronic mail between personal computers has become widespread. Such an e-mail system for transmitting and receiving e-mails is provided with a mailbox for storing the transmitted and received e-mails.

When a user sends an e-mail, an e-mail to be sent is created on a personal computer, and the created e-mail is sent to another personal computer via a communication network. At this time, the transmitted e-mail is stored in a mailbox.

When receiving such an electronic mail, the receiving personal computer stores the received electronic mail in the above-mentioned mailbox. Then, the transmission / reception of the e-mail is achieved by reading out the received e-mail by the receiving personal computer.

[0005] The transmitted / received e-mail file is stored in the mailbox of the personal computer, and the user who uses the file can specify the storage attribute of the stored e-mail. That is,
You can choose to keep the email or delete it. If storage is selected, it is kept in the mailbox, and if deletion is selected, it is immediately deleted.

[0006]

By the way, in the above-mentioned conventional example, the capacity of the mailbox is usually constant.
Therefore, there is a limit to the number of emails that can be stored. For this reason, when the number of e-mails selected to be stored increases, there is a problem that the capacity of the mailbox becomes insufficient and the storage cannot be performed.

As a method for dealing with this,
It is conceivable to add a storage device, but this method is not preferable because it involves a problem of increasing the cost.

[0008]

SUMMARY OF THE INVENTION Accordingly, the present invention extracts a read e-mail read by a user from a transmitted sent e-mail and a received e-mail received from transmitted and received e-mails. Transmitting and receiving means 6 and condition input means 2 for inputting conditions for determining the importance of the transmitted e-mail and / or the read e-mail.
And condition recording means 3 for storing the conditions input to the condition input means 2; and condition judging means 4 for judging the importance of the transmitted e-mail and / or the read e-mail based on the conditions. A compressing means 7 for compressing an electronic mail determined to be insignificant by the condition determining means 4; a compressed electronic mail; and an uncompressed electronic mail determined to be important by the condition determining means 4. Provided is an electronic mail system comprising an electronic mail recording means 9 for storing mail.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An electronic mail system according to the present invention will be described below with reference to the drawings. 1 is a user,
2 is a condition input device, 3 is a user condition recording medium, 4 is a condition determination device, 5 is a timer, 6 is a transmission / reception device, 7 is a compression encryption device, 8 is a display device, 9 is an e-mail data recording medium, and 10 is an electronic device. A mail system 11 is an electronic mail server.

First, the user 1 inputs user conditions in advance to the condition input device 2 in the electronic mail system 10. The user conditions include, for example, a date for deciding the year and month before the data to be processed, a specific character string included in the data to be processed such as an address, a timing condition indicating a timing of compression execution, and the like. Is included. Then, the user condition input in this manner is stored in the user condition recording medium 3.
Is stored in

The receiving unit of the transmitting / receiving device 6 receives the electronic mail from the electronic mail server 11, and the transmitting unit of the transmitting / receiving device 6 transmits the electronic mail to the electronic mail server 11. The e-mail received in this manner is opened by a user operation, sent to the output unit of the display device 8, and displayed. The user views the displayed electronic mail, and the electronic mail thus viewed is treated as a read electronic mail. In addition, the e-mail to be transmitted is edited while being displayed on the input unit of the display device 8 by the user.
The actually transmitted e-mail is treated as processed e-mail.

[0012] Of the above-mentioned transmitted e-mails and received e-mails, the read e-mail is sent from the transmitting / receiving device 6 to the condition judging device 4.

The condition judging device 4 judges whether the transmitted e-mail or the already-read e-mail satisfies the compression execution condition in accordance with the user condition input to the condition input device 2 in advance. Here, when the date is set as the user condition, the date of the timer 5 is used.

[0014] Specifically, based on the judgment that the mail before the year and the month is not so important, it is possible to input the date or to judge that the predetermined destination and destination are not very important. To determine the importance of each e-mail, enter the address and name of the recipient and recipient, or enter the case name or keyword for items that are not so important about the content of the e-mail Enter the condition of

When it is determined that the e-mail is not important, that is, when the compression execution condition is satisfied,
The e-mail data is sent to the compression / encryption device 7, where the data is compressed and, if necessary, encrypted, and stored in the mail data recording medium 9. On the other hand, when the above-mentioned e-mail does not correspond to the compression execution condition, the e-mail data is not compressed and the mail data is recorded on the mail data recording medium 9 as uncompressed e-mail data.
To save.

The timing of compressing the e-mail may, of course, be performed at a predetermined time interval according to a user's instruction.

When the stored e-mail data is viewed again, the uncompressed e-mail data is sent directly to the output unit of the display device 8 and displayed, and the compressed e-mail data is decrypted by the compression encryption device. And, if necessary, the code is decrypted and sent to the output unit of the display device 8 for display.

[0018]

As described above, according to the e-mail system according to the present invention, e-mail data having high importance is extracted according to the conditions input in advance, and the e-mail data is not compressed. Therefore, the e-mail can be opened without losing the processing time even when browsing again, and the amount of data stored in the recording medium can be effectively reduced by compressing the e-mail data of low importance according to the above-described conditions. It has the effect of being able to do so.
