For example, 100 advertisement keywords are preset, and if the email contains 10 or more than 10 advertisement keywords, the email is determined to be an advertisement email.
In addition, an anti-spam filtering system can be arranged, and whether the e-mail is the advertisement mail or not can be discriminated by the filtering system.
And distributing the non-advertisement mail to the non-advertisement distribution server and distributing the advertisement mail to the advertisement distribution server according to the judgment result.
Preferably, when determining the attribute of the e-mail, the e-mail may further include an illegal e-mail, that is, the type of the e-mail is classified into an advertisement e-mail, a non-advertisement e-mail, and an illegal e-mail. And if the content of the e-mail comprises part of preset illegal keywords, judging that the e-mail is an illegal mail. The illegal mail mainly refers to an electronic mail related to illegal information dissemination such as violence and anti-government, and if the electronic mail is judged to be an illegal mail, the electronic mail is refused to be distributed.
The present embodiment transmits an advertisement mail through an advertisement distribution server that exclusively transmits advertisement mails, and transmits a non-advertisement mail through a non-advertisement distribution server that exclusively transmits non-advertisement mails. The non-advertisement distribution server does not send the advertisement mails, and the non-advertisement distribution server cannot be added into the blacklist by the server of the other side, so that the technical problem that the non-advertisement mails cannot be sent in time due to the fact that the IP address of the server is added into the blacklist can be effectively solved.

For example, the ratios may be divided into several classes > 50%, 30-50%, 20-30%, 10-20%, 0-10%. Specifically, the probability of rejecting the advertisement mail may be the same as the above ratio, or may be calculated by other factors. For example, the probability that the mail is rejected is determined in conjunction with the content of the advertised mail and the credit rating of the mailbox address that sent the mail.
And step 206, distributing the advertisement mail to a sub advertisement distribution server corresponding to the probability of rejecting the advertisement mail according to the probability of rejecting the advertisement mail.
The advertisement distribution server can be divided into a plurality of sub advertisement distribution servers according to the probability of rejecting the advertisement mail. For example, if it is determined that the rejection probability of the advertisement mail is 30%, the advertisement mail is distributed to a child advertisement distribution server containing the rejection probability of 30%.
