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

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.
