Sorry my mistake.  I should have made the same substitution.  So let
me sum up:

I believe that the 'address subbed to thelist' is passed to the MTA
along with a list of other ones.  The MTA goes through the list and
e-mails the addresses individually.

I believe that the 'final recipient' is handled by the receiver's MTA.
If the receiver's uses aliases, .forward, procmail, etc., their local
MTA will rewrite the header and send it to the final recipient.

So I think that our MTA has to write the 'address subbed to the list'
into the headers.

Of course, I could be wrong, so if you can pursue the other option
(mailman header munging), that would be useful too.
