Linux系统下基于postfix垃圾邮件过滤方法

An Empirical Study of Spam Filtering in Linux System Based on Postfix

针对垃圾电子邮件存在的安全隐患,对Linux系统下postfix垃圾邮件过滤方法进行深入研究,并在此基础上设计了结合smtp和ssl机制验证客户端发送邮件人的身份的方法。实验表明:该方法能够有效阻止垃圾邮件入侵用户邮箱,提高了邮件系统的安全性,实现了指定用户的邮件收发功能。

To deal with the safety hazards existing in junk E-mail, the paper discussed postfix spam filtering method in depth underthe Linux system. And on this basis client identity mechanism combined with the SMTP and SSL verification email was furtherdesigned. The experiment results showed that the method could effectively prevent spam from invading the user爷s mailbox andimprove the security of E-mail system; therefore, it realized specified user爷s email sending and receiving function.
