Hm.  What about something that sits between the MDA and Mailman and
makes this translation?  Does that seem feasible?  Would this require
changing the alias for each list, for example, or is there another way
to do this from within the MTA?  I'm using postfix.

I'm willing to require that all addresses that Mailman sees be the
"external" address (@foobar.com), and the internal addresses can all be
easily mapped to that external address by stripping off the internal
domain and adding the external domain.  The reverse is not true because
there are multiple Exchange servers with different addresses.

As I said, that would be good but is utterly out of the question.  The
people in charge of all the mail infrastructure will never do that.
