System and method for preventing spam mails

摘要

A system and method for preventing spam mails. A spam mail information collection server extracts base information for spam mail determination from header information of spam mails received at false mail addresses, databases the extracted spam mail determination base information and provides the databased spam mail determination base information to at least one mail server. The mail server receives the spam mail determination base information and stores it in a database. Upon receiving a new mail, the mail server analyzes header information of the received new mail, searches the spam mail determination base information database for the analyzed header information to determine whether the new mail is a spam mail, and blocks the reception of the new mail if the mail is determined to be a spam mail.
