Java Mail Server is a Java SMTP and POP3 e-mail server. This project was inspired by and based on the CRSMail project written by Calvin Smith. This project exists for everyone who is interested in running their own email server quickly and easily.

The goal of JES is to provide an easy to use and reliable email server that can be quickly and easily setup. JES attempts to provide a powerful server using the minimal number of configuration settings and project size.

JES 2.0 is finally here! 2.0 is now in Beta and available from the downloads section below. It provides MANY additional features (see the for the full details), including much improved security including TLS/SSL support.

Support for JES is available in the Google Group.

Using JES as a testing tool? There is now an Eclipse Plug-In for JES. It allows you to start, stop, and configure JES from Eclipse.

If you are ready to start using JES, please see the Download and Install sections below for instructions on downloading and configuration JES. Both versions, and the source code are available for download from the Download section.
