I would have to know more about his actual T-bird configuration to
comment on that.

As Chris says, if he has more than one T-bird identity, when he composes
a reply, the From: in the composition window is a pull-down list from
which he can chose the identity he wants. I think this normally is the
identity that the original was addressed to, but he should have control
in any case.

Delivered-To: is added by Postfix and perhaps other MTA's in the
delivery chain (It's used by Postfix to detect mail loops). Envelope-To:
is added by some MTA. Mailman has nothing to do with either.

I use T-bird, but I'm not sure exactly what headers it uses when
selecting a default From: address on a reply, but the user can always
select a different one, although that's a step that's easily forgotten.
