[Logo]Postfix Source Code

Postfix is released under a dual Eclipse Public license (EPL 2.0) and IBM Public License (IPL 1.0) (Postfix 3.1 and earlier are released under the IPL 1.0).

All Postfix source code is signed with Wietse's PGP key. See ftp://ftp.porcupine.org/mirrors/project-history/postfix/ for a more extensive archive of stable and experimental tarballs.

Postfix 3.3 stable release candidate

Release candidates are made available so that people can adopt fixes before a new Postfix stable release comes out. The code may still change as new defects are discovered.

Postfix 3.4 experimental release

New features are tested in experimental releases. They become part of the next official release once the code has not changed for a significant amount of time. Although this code is still subject to change, it runs on all of Wietse's systems so it is production quality.

Experimental releases are called "Postfix a.b-yyyymmdd", where a.b is the next official Postfix release and yyyymmdd is the release date.
