Standard

100% pure Java Mail server designed to be a complete and portable enterprise mail engine solution.

Apache James Server is able to store user and message data either in any JPA-compatible database, in Cassandra (allowing fast, reliable, even real-time replicated storage) and on a file-system (Maildir).

Provides a powerful, flexible mail application engine through support for the Apache Mailet API. With its Mailet pipeline architecture, Apache James Server can be used not only to provide standard e-mail services, but also to implement custom e-mail applications.

Developer-Friendly

Apache James Server 3.0 is now built on top of Spring 3.0 or Guice in replacement of the Avalon Application Framework. With Spring, We keep the good development practices introduced by Avalon such as Component Oriented Programming and Inversion of Control. The stable and robust Spring container provides a strong foundation for the Apache James Server.

The internal and exposed APIs for this 3.0-beta4 release are under current validation and are expected to be subject to change - read more.

Performant

A special focus has been brought to the performance: Apache James Server can process more than 100 mails per second. Deployed in production environments and has proven itself to be a robust and high performance mail solution. Tests indicate that version 3.0 is able to maintain a constant mail throughput rate of thousands of messages/minute for continuous periods - read more
