Changing MTAs on Mailman box
Hi All,
I am looking at changing our MTA from Sendmail to Postfix. The physical box is staying the same, nothing is changing other than the MTA on the box.
Is there anything on the Mailman side that I need to do after the change?
I looked at the Postfix integration section in the installation manual, http://www.list.org/mailman-install/postfix-integration.html and am just a bit unsure if these are the steps to take since this is an existing Mailman installation.
Thanks for an pointers. Bryan

The Postfix integration may recommend putting cron scripts and init scripts in a different place. Make sure that any such scripts and their invocations installed for Sendmail are removed or moved to the locations expected by Postscript. You probably don't even have to move them since Mailman is presumably not going to change, so there may be nothing to worry about, but duplicated scripts are a common source of problems.
Other than that as far as I know the only thing you need to do is configure Postfix to forward mail to Mailman.

There shouldn't be any difference. If you're on a Debian system or derived there may be a postfix-to-mailman script around somewhere; make sure that is not active. The installation in the Postfix integration page you cite is preferred. And it is easier for us to help you with any problems if you use that rather than the Debian script.
Mark S. may have further advice, but I'm sufficiently confident that I recommend that you just get started. :-)

The first question is how does your sendmail deliver to Mailman. The "normal" configuration uses aliases which are maintained manually as lists are created and deleted.
If you have a set of Mailman aliases in, e.g., /etc/aliases, You may not need to do anything and things may work fine, but it is also possible you will get "group mismatch errors" from Mailman's mail wrapper.
You can set up Mailman/Postfix integration. To do that, you should do the generic Postfix things at http://list.org/mailman-install/node12.html and the integration specific things at http://list.org/mailman-install/postfix-integration.html.
In addition if you have lists in Postfix virtual domains you need to do the things in http://list.org/mailman-install/postfix-virtual.html.
But you can ignore all that and continue to do aliases as you've done for Sendmail.
If you have further questions, pleas tell us how Sendmail is currently delivering to Mailman, and if via aliases, how those are generated.

Thanks Stephen & Mark.
Mark, Sendmail uses the manually created Aliases to deliver to Mailman. But I think I'd rather have the integration with the aliases automatically created.
I'm sure that I'll have further questions since this will be my first Postfix install, but I'll find a proper Postfix mailing list to ask the stupid Postfix questions. I'll reserve the stupid Mailman question for here ;)
Thanks, Bryan

If you find one, could you tell this list where it is? The one I found a few years ago, postfix-users@yahoogroups.com, hasn't had any messages since July 2014.
