随着计算机网络的发展，垃圾邮件问题和邮件欺骗问题变得越来越严重，给广大网民带来巨大危害。为了保障网络公共安全，减轻垃圾邮件和钓鱼邮件对网络用户的危害，基于深度包检测技术设计实现了一个针对钓鱼邮件的监控系统。通过数据包捕获技术和协议解析技术对电子邮件进行还原，实现对邮件内容的检查，结合关键字匹配技术实现了对垃圾邮件和钓鱼邮件的检测和报警。实验证明，通过协议分析与数据包还原技术，可以对垃圾邮件和敏感邮件进行过滤。

With the development of Internet,the problem of spam and phishing email becomes more and more serious,it has done harm to cyber citizens. In order to strengthen the public network security,reduce the harm of spam and phishing email,design and realize a moni-toring system for phishing email based on DPI. Adopt the packet capturing technology and protocol analysis technology to email rever-ting,succeeding in inspecting the email content,then apply keywords matching technology to detect the phishing email and give a warning for it. The experiments show that it can detect the spam and phishing email by the protocol analysis technology and packet restoration technology.
