Yes, it is possible to do this. What you describe is almost exactly
what cPanel does in their modified Mailman. There are other patches
around, but IMO, none are totally satisfactory. At least one user has
recently posted that he is working on his own implementation.

This feature, but not necessarily this implementation, will be in MM 3.

The main thing you need to do is arange for mail delivery
(postfix-to-mailman.py in your case) to deliver mail addressed to
list at example.com, list-bounces at example.com, etc. and also
list-bounces+xxx at example.com and list-confirm+xxx at example.com to the
appropriate list-example.com list.

If you are willing to use the list-example.com names for the web
interface and elsewhere, that may be enough, but you will undoubtedly
discover other things that need to be 'fixed'.
