Postfix license change

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).

About this source-code archive

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 3.11 stable release

See below for past stable releases that are still supported and for releases that are no longer supported.

Stable releases do not change except for bugfixes and for portability fixes. New features are tested out in experimental releases (see below).

Stable releases are called "Postfix a.b.c", where a is the major release number, b is the minor release number, and c is the patchlevel.

Source code changes since Postfix Version 3.11.0.

Postfix 3.12 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 named "postfix-a.b-yyyymmdd", where a.b is the next official Postfix release and yyyymmdd is the release date.

Postfix non-production release(s)

Non-production releases contain major changes that need to be tested further before they become part of a regular experimental release.

A non-production release usually includes all the features and fixes of the regular experimental relase of the same or earlier date.

None at this time.
