中小企业web邮件系统的设计与实现

database to manage user information、mail information and system configuration parameters data. For the sake of security, mail sending and receiving and spam filter system have also been tested. Testing the prototype WebMail system. The result shows that the system implements the basic function of a mail system, and its performance meet the need of a middle level mail server.

In the last part of the paper, the author explains the current status of the study and points out the characteristics of the system and its limitations. The follow-up problems of the system has also been described.
