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

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

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
 and the integration
specific things at
.

In addition if you have lists in Postfix virtual domains you need to do
the things in .

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.

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. :-)

[Mailman-Users] Changing MTAs on Mailman box

[Bryan Carbonnell]

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
