基于SMTP会话控制的主动式垃圾邮件过滤技术的研究

An Active Model Spam Filtering Technology Based on SMTP Session Control

随着垃圾邮件传播手段的不断变化,传统基于内容的反垃圾邮件技术正面临着严峻挑战,本文提出了一种基于smtp会话控制的主动式垃圾邮件过滤技术。该技术通过分析垃圾邮件的通信会话过程中的特征信息,在MTA会话连接的不同阶段实现垃圾邮件的识别与拦截,并设计了一个垃圾邮件过滤网关并进行过滤实验。实验结果表明,提出的技术具有良好的识别效率和准确率。

Spam has drawn high attention of the researchers recently. However, there is still no method available to anti - spam actively. The author designs an e - mail filter examination system based on the SMTP control filter technology.
