摘　　要：垃圾已成为网络、信息系统和主机的主要安全威胁之一。导致垃圾邮件泛滥的根本原因是SMTP协议不能制止邮件发送者的某些欺骗行为。邮件过滤技术是在SMTP协议基础上,运用针对垃圾邮件发送特征和邮件内容的多种过滤技术,在一定程度上弥补了SMTP协议的缺陷,从而限制垃圾邮件的传播。Spare is one of the major threatens to the security of network, information systems and the computers. The fundamental cause of spare flooding is that SMTP protocols can not countercheck some cheat from the Spam senders. The e - mail filtering technology, based on SMTP protocol, addresses the fault of SMTP protocol to a certain extent by using multi - filtering technology directed at sending features and content of Spare, thereby restrict the spread of Spare.
