Implementing a SPAM Filtering Gateway with Apache James

This paper discusses the configuration of a SPAM Filtering Gateway using the Java Apache Mail Enterprise Server, James, developed by The Apache Software Foundation. The configuration describes the setup of an Apache James mail server to process incoming mail for spam properties before delivering the mail to an internal server. It focuses on reducing the processing load of the internal mail server by dropping mail relay attempts, flagging messages as SPAM for end-user management, and lowering exposure to common vulnerabilities found in many of the popular mail servers on the market today. Both RedHat Linux 9.0 and Windows 2000/XP installations are discussed, as well as performance and security considerations.
