摘　　要：现有基于SMTP协议和客户/服务器模式的电子邮件系统采用类似路由器的转发机制,由于邮件服务器无法验证最初发送者的身份或源地址的真实性,导致垃圾邮件泛滥,而现有基于内容分析的过滤机制误判率高,经常导致邮件丢失。通过分析邮件头中的源地址信息,提出基于虚假发信人地址的垃圾邮件检测与过滤方法Anti-FSASpam, 并在此基础上开发实现了虚假发信人地址垃圾邮件的检测与过滤系统,经检验,该系统能有效检测与过滤虚假发信人地址垃圾邮件,同时能保证正常邮件不会被错误过滤。Current email systems based on SMTP protocol and C/S structure adopt the relaying mechanism which is similar to that of routing, as the server can not verify the authenticity of the original email sender, it always leads to the spread of spam, while existing solutions to spam based on content analysis get high misjudgment rate and lead to lost of emails. This paper studied and analyzed the header structure of Email, and proposed a new spam detection and filtering method FSA-Spam which can effectively detect and filter Spam with forged sender address, and based on which a forged sender address spam detection and filtering system was designed and implemented.
