反垃圾邮件系统设计摘要电子邮件是人们使用较多的一种通信方式,然而在给人们带来大量快捷的同时,其副产品垃圾邮件也给人们的生活增添了无穷的烦恼。如今我们接收到了大量的垃圾邮件,这对收件人的时间、带宽和存储资源产生了无效占用,网络链路因此造成拥塞,它还被作为不良信息的载体被到处散发。因此本文主要讨论了一些常用的反垃圾邮件技术,主要包括关键字匹配技术,实时黑名单技术,反向查询技术,详细介绍了贝叶斯技术的基本原理及其代码实现,最后对应用实验的不足进行了总结并提出了进一步的研究方向。关键词:反垃圾邮件,关键字匹配,实时黑名单,贝叶斯算法 D esign of anti-spam systerm Abstract E-mail isone manner munication between us that we use frequently , for its convenience and rapidness ,but spam whose byproduct bring endless bother toour life. Now , the amount of the spam we received has exceed ed that of need ed mail , the time , bandwidth and memory resource of addressee s’ is tied up ineffectively , thereby , network connection generate congestion .The text discusses men anti-spam technology , such as keyword-matching , real-time black list , reverse query , and elaborate on basic theory and code realization of Bayesian technology , at last the thesis summarize the lack of the experiment and bring forward the direction of father research .
