摘　　要：文章在分析了主流反垃圾邮件产品的基础上,提出了一个基于网络侦听方式的解决方案及系统的设计与实现。该系统最大限度地降低了对网络和邮件服务器性能的影响,同时能够适应高速网络环境。对垃圾邮件的分析采用特征匹配的方法以进行实时拦截,避免了异常终止TCP连接所引发的邮件重发问题。目前该系统已成功应用在工程中。In this paper, a scheme and corresponding system is proposed and implemented on the basis of analysis over the most popular anti-spam products and the spam filtering technologies. The system has the smallest influence on the performance of network and mail server. The system is based on the mode of sniffing, and its architecture make it adapt to large scale network. The realtime blocking of spam adopt character matching technology, and efficiently prevent mail server from resending spare caused by abnormally reset the connection of TCP.
