== How do I configure postfix_to_mailman.py? ==
First of all, postfix_to_mailman.py is a third party module neither created nor distributed by the [[http://www.list.org/|GNU Mailman project]]. It would probably be rarely if ever used but for the fact that it is distributed by Debian (and hence Ubuntu) as part of their Mailman package.<<BR>><<BR>>postfix_to_mailman.py is part of an alternative to aliases for delivering list mail from Postfix to Mailman. It only works well in an environment in which all Mailman list addresses are in a dedicated domain in which there are no non-list addresses as postfix_to_mailman.py will only deliver to Mailman list addresses and a few others such as 'postmaster', 'abuse' and 'root', all of which get resent to the Mailman admin.<<BR>><<BR>>postfix_to_mailman.py is an alternative to and is incompatible with Mailman delivery via aliases. If you are configuring both Mailman aliases and postfix_to_mailman.py, you are making a mistake.<<BR>><<BR>>In the spirit of helping everyone who wants to use Mailman be successful in its use, those who support GNU Mailman will try to help you with your use of postfix_to_mailman.py, but please be aware of the following. Most issues with postfix_to_mailman.py are Postfix configuration issues, and the GNU Mailman project is not a primary resource for Postfix support. Most people are only aware of postfix_to_mailman.py because it comes with the Debian/Ubuntu Mailman package and the GNU Mailman project is not the primary resource for supporting Debian/Ubuntu packages. See [[../I installed Mailman from a package or I followed a HowTo document. Where do I go for help?|this FAQ]]. The official position of the GNU Mailman project is that postfix_to_mailman.py offers no advantage over the officially supported [[http://www.list.org/mailman-install/postfix-integration.html|Postfix-Mailman Integration]].<<BR>><<BR>>Before trying to use postfix_to_mailman.py, you should see some of the hits at this [[http://www.google.com/search?q=site:mail.python.org+inurl%3Amailman+postfix_to_mailman.py|Google search]] including [[http://mail.python.org/pipermail/mailman-users/2012-September/074017.html|http://mail.python.org/pipermail/mailman-users/2012-September/074017.html]].<<BR>><<BR>>
