## About

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 of 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.

### James from a technical point of view

Complete portability (100% pure JVM: Java & Scala)
Built with Java 11 and running on the Java RE 11.
James Components:
- Emailing protocols: SMTP, LMTP, POP3, IMAP, ManageSieve, JMAP
- Mailet container: independent, extensible and pluggable email processing agents
- Storage API: Mailbox API / Search API / User API
- Storage Implementations: Cassandra / PostgreSQL / HSQLDB / MySQL / OpenSearch...
- Administration: JMX / REST / Command Line
- James Core

Your James server can also be used as Mail Transfer Agent, by enabling only SMTP or as a IMAP Mail Delivery Agent.

## James is a living Open Source project (all developments and implementations are based on open technical standards), any function which is not already available from can be developed!

## Get Started With James

### Get Started With the official binaries

- →DOWNLOADS:
  The Apache James project wires together the different libraries composing James to provide a running services, ready to download on the Apache mirrors. See our download page.
  Follow our installation guide.

### Get Started With James And Docker

- → WHAT WILL YOU TRY:
  Here you will try James server version 3.8.2 thanks to an 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: user01@james.local, user02@james.local, user03@james.local, with their default password being 1234.
  Note: this James server will respond to IMAPS port 993 and SMTPS port 465.
- →STEPS YOU HAVE TO FOLLOW:
  Pull and run the James image with the following single command:
  `docker run -p "465:465" -p "993:993" apache/james:demo-3.8.2`
  Then, connect this image with for instance, Thunderbird. This tutorial covers more in depth user and domain creation, as well as thunderbird setup.
- →ALTERNATIVES:
  Instructions that do not imply docker are also available here.
- →Distributed James server
  Recent work of the Apache James project did lead to a James product that leverages a distributed mail server, using storage technologies like Cassandra, OpenSearch, RabbitMQ, and objectStorage (S3/Swift).
  Feedback on this product is welcome.
  This product can be executed via docker-compose or you can follow its standard installation guide

## Roadmap

- MAIN GOALS
  - →Providing a distributed mail server, fully horizontally scalable.
  - →Maintaining a standalone version suitable for a single server, based on JPA.
- INCOMING WORK
  - →Rework our documentation with Antora, specify it on a per-server basis for ease of use. Preview...
    We will furthermore target servers to identified use cases, formulated in non technical terms: Basic Server, Advanced Server and Distributed Server.
  - →Promote guice based applications.
    Spring server will be deprecated. A summary of community call describing this item can be found here.
    Guice adoption schedule:
    1. Promote Guice artifacts on the download page as part of `3.7.0`
    2. Deprecate Spring artifact as part of `3.8.0`
    3. Remove Spring artifact as part of `4.0.0`
  - →Continue improving JMAP RFC-8621 support. See this JIRA for some further possible developments
  - →Feel free to add your own items here: see Contribute.

## James use-cases

Linagora
OpenPaaS

##

At LINAGORA, we chose JAMES as the Mail Delivery Agent of our OpenPaaS product:

- For easy administration of email load balancing and high availability
- To allow email interactions with the platform
- To use the JMAP protocol (the browser interacts directly with the mail server)

Our deployment currently allows serving a hundred users over JMAP, SMTP and IMAP.
