Description

  The present invention relates to an e-mail management system, and more particularly to an e-mail management system that can take measures against spam mail.

  Recently, the spread of electronic mail using personal computers and mobile phones has been remarkable and is being used on a daily basis.

  However, in such electronic mail, there is a problem of the presence of junk mail that is sent unilaterally even though the recipient does not need it.

  These spam mails include contents that cannot be read, those that send many mails, and those that are infected with a virus. Countermeasures against this spam mail are very important for the recipient.

  Conventionally, as a countermeasure against spam mail, an email address that has been found not to be a sender sending spam email is registered in advance, and e-mail is received from this registered email address. You can register in advance a whitelist method that allows emails and email addresses that are known to be spammer senders, and send emails from this registered email address. A black list method for rejecting reception is known. Also, the blacklist method is a method for analyzing and scoring “like spam” based on the name of the drug in the body of the email and the number of URLs written on adult sites, etc. Sometimes used together as an auxiliary (see Non-Patent Document 1, Non-Patent Document 2, Non-Patent Document 3, and Non-Patent Document 4).

  For example, the user whose user ID is “AA” operates the personal computer 3a and inquires of the mail server of his / her mail address of the mail servers 5 and 6 whether there is a received mail (C-1).

  If there is no received mail (C-2), the process is terminated as it is. When there is a received mail (C-2), the personal computer 3a communicates with the database server 1 and performs user authentication (C-3).

  The database server 1 records a record corresponding to the group ID of the group to which the user authenticated in step (C-3) belongs from the black list table in FIG. 7C and the white list table in FIG. Is extracted, and the black list and white list used by the group are acquired and transmitted to the personal computer 3a (C-4). As other processing, the database server 1 may simply transmit the table to the personal computer 3a, and the record extraction processing or the like may be performed by the personal computer 3a.

  The personal computer 3a collates (C-5) the sender address of the received mail obtained by the inquiry in step (C-1) with the mail address of the black list acquired in step (C-4). Receiving the electronic mail is rejected (C-6). In step (C-6), the mail may be received without refusal and stored in the junk mail folder.

  If not in the black list, the sender address of the received mail by the inquiry in step (C-1) is collated with the mail address in the white list acquired in step (C-4) (C-7), and if they match The electronic mail is received and stored in the reception folder (C-8).

  If it is not in the white list, it is unclear whether it is a junk mail or a necessary mail, so the electronic mail is received and stored in the hold folder (C-9).

  The e-mail stored in the hold folder is checked by the user himself / herself, and when it is determined whether the e-mail is junk mail or necessary mail, the sender address is obtained by the process shown in FIG.
