Why involve mailman? Why not use either the alias feature or the address
rewriting feature of your MTA?
But don't you have a larger problem? If the user is still using his old
address and thus receiving mail at his old address and you change his
address to the new domain when mailman sends the mail to the list then
how is somebody going to respond to that user? It's going to go to the
new address right where he won't see it (or were you planning on
aliasing these as well?).
