I don't know if Mailman is that smart, although if it's not, that's an
excellent enhancement that I hope someone will eventually develop.  (One
problem is that Mailman doesn't send its own mail -- it uses the local MTA
instead and then parses the bounce message -- which means that it's hard
for it to come by that information.)
