Zhao Xiaoming Zheng Shaoren (Institute of Communications Engineering, Science and Technology University of P.L.A, Nanjing 210016, China)  
How to protect the E-mail system from invasion of computer viruses and mail bombs has become increasingly protruding due to the recently wide use of E-mail. In this paper, the necessity, functional structure and deployment strategy of electronic mail filter system are analyzed and discussed. Consequently, a relevant conclusion is drawn: building a SMTP mail filter system with capabilities of rule filtering, scanning attachments and removing harmful scripts is the base of a mail protection system. On one hand, we can extend its functions and make it an independent mail service system. On the other hand, we can make some filter plug-ins for some special message transfer systems that do not support SMTP. All of these make a total solution for mail protection system.
