摘要
为了遏制网络中大量存在的垃圾邮件,需要对网络中传输的邮件信息进行获取,以实现垃圾邮件的恰当过滤。本文通过分析邮件传输的两种方式,讨论了与邮件信息获取相关的若干问题,主要包括网络数据包的捕获与重组、基于SMTP/POP3协议的邮件信息获取技术以及基于HTTP协议的Webmail邮件信息获取技术。实际应用表明,本文所讨论的邮件信息获取技术具有较大实用价值,为实现垃圾邮件的过滤奠定了重要的技术基础。
To reject spam on the intemet, mail information transmitted on the network should be captured in order to filter the spam properly. By analyzing two typical ways through which e-mails are transferred, this paper discussed some issues about mail informa- tion extraction, including capturing and reordering of the network packages, extracting of mail information based on SMTP/POP3 and HTFP.
