[Mailman-Developers] Sendmail to Postfix

I'm converting over to POSTFIX from Sendmail (well actually I can switch back and forth between the two in RedHat 7.3) and I'm running Mailman 2.0.13 without problems (only problem is with large lists, here I believe Postfix can help me there). Postfix has more tweak options that's why I want to switch. When I make the change to "Postfix" is there anything I need to change on Mailman to make it run with Postfix, in other words will I break anything?
