mailman-users at python.org is not the best resource for generic Postfix
questions. I suggest you join the postfix-users at postfix.org list and
post there. See <http://www.postfix.org/lists.html>.

That said, I think you can accomplish what you're trying to do with
sender_canonical_maps instead of smtp_generic_maps.

Also note, if you rewrite the -bounces address, you will break Mailman's
automated bounce processing and the helpdesk will have to deal with
bouncing addresses manually.
