邮件过滤器系统的设计与实现

在对垃圾邮件及其防范技术进行全面分析与比较的基础上，针对传统特征过滤技术的被动防范和能力不足问题，提出了利用多邮件地址分类使用的主动防范技术，并通过一个使用户可以自主地扩展自己邮件地址的原型系统，与传统的特征过滤技术配合，形成了更为有效的垃圾邮件防范能力。

Design and Implementation of Email Filter System

Based on the comprehensive analysis of junk mail and defense techniques, an active defense way with which multi email addresses are classified for different people or group is proposed because of the passive defense and insufficient ability of traditional characteristic filter technique. Combined with the traditional characteristic filter technique, using a prototype email filter system that enables user to extend their email address freely, the active defense way may be more powerful.
