摘　　要：电子邮件泄密越来越引起人们的关注,基于SMTP和POP3协议的电子邮件审计已经比较成熟,然而对众多大型门户网站的WebMail的审计却是一个难点。各大厂商WebMail协议不统一,把WebMail当作http的uplayer协议处理,设计并实现了一个在Linux下基于模板的WebMail审计系统。WebMail模板的特色在于设计了一个用于标志邮件正文和附件的glueid,通过它能够很好地将正文和附件合并为一封完整的邮件。系统采用了经典的单模式匹配KMP(Knuth-Morris-Pratt)算法对邮件内容进行审计,提高了审计效率。E-mail leaks is increasingly causing people＇s attention,though the e-mail auditing technology based on SMTP and POP3 is relatively mature,WebMail auditing on numerous large-scale web portals is indeed a difficulty.The protocols of WebMail the major manufacturers used are different from each other.In this paper the authors deal with the WebMail protocol as an uplayer protocol of http and design and implement a template-based WebMail auditing system on Linux.The specialty of the WebMail template is that a flag named ＂glueid＂ is designed for marking a mail message body and its attachments;through this flag it is able to well merge the message body and the attachments into a complete e-mail.The system uses classic single-pattern matching KMP algorithm to audit the contents of email so that the efficiency of auditing is improved.
