The below suggestions to procmail before posting to the list requires manual configuration each time you set up a new list.

Is there a simple automatic way to achieve this?

I have an Ubuntu server running Mailman 2.1.9, Postfix 2.5.1 and procmail 3.22. I have gotten mailman and postfix to work correctly using the postfix-to-mailman.py file.

How does one integrate procmail into this mixture with the postfix-to-mailman.py file? Is it possible to do this or does one have to configure postfix and mailman differently in order to have procmail do some filtering?

I understand that postfix_to_mailman.py is packaged with the Debian/Ubuntu Mailman package, but it is 3rd party software, not supported (officially at least) by the GNU Mailman project.

That said, one possibility might be to modify the mailman transport in /etc/postfix/master.cf to invoke procmail instead of postfix_to_mailman.py and then have procmail invoke postfix_to_mailman.py for the mail it wants to deliver.

Another possibility is to modify postfix_to_mailman.py to invoje procmail instead of Mailman's mail wrapper and then have procmail invoke Mailman's wrapper to post the mail.
