The operation of the unnecessary mail filtering system according to the embodiment of the present invention will be described with reference to FIGS.
In the following description, the network 100 will be the Internet.

First, the filtering mail server 2 is provided with a virtual space (WEB area) for checking mail (FIG. 5).
In step S1), the recipient terminal 3A that has accessed the WEB area displays the header information and the mail sender information of the mail that came to its own mail address (see FIG. 3).

That is, when the recipient terminal 3A accesses the filtering mail server 2 through a predetermined authentication, the recipient terminal stored in the mail storage unit 22 is stored in a predetermined area of the WEB mail device 25 of the filtering mail server 2. Received mail information including header information and mail sender information of the received mail addressed to the user 3A is generated.

Therefore, the receiver terminal 3A can read and display the received mail information by accessing the predetermined area of the WEB mail device 25. The reception terminal 3A accesses the predetermined area of the WEB mail device 25 and reads the received mail information every time the mail is received, every predetermined period, every predetermined number of times of access, or the user of the receiver terminal 3A. It may be optional.

Further, the received mails to be filtered are based on, for example, a predetermined size or more, presence / absence of an attached file, etc., and may not be all the received mails.

The user of the receiver terminal 3A accesses a predetermined area of the WEB mail device 25, and selects mails based on the received mail information (source and summary information) displayed. At that time, the user of the receiver terminal 3A puts in a keyword in advance, and takes appropriate measures (color change, underline, emphasis, etc.) so that the e-mail containing the phrase can be easily understood, and the result is removed. The selection may be made easier (see FIG. 4).

For example, when words such as “encounter” and “adult” are stored in advance in the unnecessary mail information management unit 23 of the filtering mail server 2 and an electronic mail is received and stored in the mail storage unit 22. ((Step S2 in FIG. 5)
S3), the mail reception control unit 24 determines whether or not the stored content of the unnecessary mail information management unit 23 and the received mail stored in the mail storage unit 22 match (steps S4 and S in FIG. 5).
5) If there is a coincident portion, measures such as color change (for example, in red), underlining, and emphasis are taken on the corresponding portion of the received mail information in the predetermined area of the WEB mail device 25.

The user of the receiver terminal 3A selects the received mail. In the example shown in FIG. 3, header information from the users (three parties) of the sender terminal 1X, the sender terminal 1Y, and the sender terminal 1Z is confirmed, and mails from the sender terminal 1X and the sender terminal 1Y are received. , Rejecting the mail of the sender terminal 1Z (see FIGS. 3 and 4).

Regarding the user (sender) of the sender terminal 1Z who has refused to receive it, the receiver terminal 3A refuses to accept the subsequent mails from the mail address, the sending server, etc. (personal defense). .

The mail from the user (sender) of the sender terminal 1Z stored in the mail storage unit 22 of the filtering mail server 2 does not need information such as the sender and header information after a certain period of time. (Steps S6 and S7 in FIG. 5).

The user of the sender terminal 1Z (sender)
When the number of mails sent from the same sender exceeds a certain number (arbitrary predetermined number), such as the users of the receiver terminals 3B and 3C rejecting the mails from In step S8), the sender of the mail is stored in the unnecessary mail information management unit 23 as a "junk mail sender" (blacklisted) (step S9 in FIG. 5).

After that, when the mail is received from the sender, the mail reception control unit 24 of the filtering mail server 2 determines whether or not the sender is a "junk mail sender" (steps S4 and S5 in FIG. 5). If it is a "sender", the reception is rejected by the measures such as not storing it in the mail storage unit 22 (overall protection) (step S10 in FIG. 5).

According to the method as described above, the junk mail can be repelled without the user frequently performing the troublesome mail reception refusal work.
