James stands for Java Apache Mail Enterprise Server!

It has a modular architecture based on a rich set of modern and efficient components which provides at the end complete, stable, secure and extendable Mail Servers running on the JVM.

Create your own personal solution for emails treatment by assembling the components you need thanks to the Inversion of Control mail platform offered and go further customizing filtering and routing rules using James Mailet Container.

Supported protocols are: IMAP, SMTP, JMAP, POP3 and more…​

The Distributed server focuses on delivering an easy-to-operate scalable mail server based on modern technologies (Cassandra, S3, ElasticSearch and RabbitMQ).

How to try James

Read more…​

Requirements: docker installed.

Here you will try James server version 3.7.0 thanks to a docker image. This James image has a default configuration using JPA (hsqldb) and Lucene. It also includes a default domain named james.local and three default users: [email protected], [email protected], [email protected], with their default password being 1234.

Note: this James server will respond to IMAPS port 993 and SMTPS port 465.

Pull and run the James image with the following single command:

$ docker run -p "465:465" -p "993:993" apache/james:demo-3.7.0

Then, connect this image with for instance, Thunderbird. This tutorial covers more in depth user and domain creation, as well as Thunderbird setup.

Instructions that do not imply docker are also available here.

Instructions for the distributed server can be found here.

How to check the compilation

Read more…​

We require maven version 3.6.1 minimum to build the project.

Simply run mvn clean install within this directory to compile the project.

Useful options includes:

  • -DskipTests to skip the long to execute resource consuming test suite that requires a docker daemon.

  • -T 4 to parallelize the build on several CPUs.

How to run James in Docker

Using the CLI

Develop on James

James requires at least JDK 11 and Maven 3.6.1 to build. Some parts of James are written in Scala so one might need to enable Scala plugin in IDE.

We maintain code examples to help you write your own extensions and wire your own servers.

This page details how to run deployment Tests.
