The Java Apache Mail Enterprise Server (a.k.a. Apache James) is a 100% pure Java SMTP and POP3 Mail
server and NNTP News server designed to be a complete and portable enterprise mail engine
solution. James is based on currently available open protocols.
The James server also serves as a mail application platform. The James project hosts the Apache Mailet API,
and the James server is a Mailet container. This feature makes it easy to design, write, and deploy
custom applications for mail processing. This modularity and ease of customization is one of James'
strengths, and can allow administrators to produce powerful applications surprisingly easily.
James is built on top of version 4.1.3 of the Avalon Application Framework. This
framework encourages a set of good development practices such as Component Oriented Programming and
Inversion of Control. The standard distribution of James includes version 4.0.1 of the
Phoenix Avalon Framework container. This stable
and robust container provides a strong foundation for the James server.
This documentation is intended to be an introduction to the concepts behind the James implementation, as well
as a guide to installing, configuring, (and for developers) building the James server.
