Architecture

James is a multi-protocol message processing and storage engine. James currently consists of:

- two mail prototcol servers (SMTP and POP3),
- a remote administration server,
- an NNTP server,
- a mail processing engine that supports the Mailet API
- file-system message storage and a message storage interface to RDBMS's
- file-system user record storage and an experimental interface to LDAP directories
- support for TLS (SSL) for POP3 and remote administration
- support for SMTP auth

James is built on top of Avalon, the Java Apache Server Framework. Versions 2.3 of James use a modified trunk version of Avalon code. Please the JAMES_PHOENIX.txt file shipped with the src for information. The `lib` directory includes date-stamped jars of the various Avalon libraries.
