[Mailman-Users] New FAQ entry: broken autoresponders

Which is the same as what I went on to say I think...

Mailman (post 1.1) does this bounce detection - presumably by looking at
the envelope sender in the first instance.  I think I'm arguing for
envelope senders of "postmaster[@domain]" and "mailer-daemon[@domain]" to
be treated as failure messages by bounce detection code too.  People with
broken autoresponders would then get treated as if their address was
failing while they took a vacation.  This appeals to me as the punishment
gets inflicted on the trouble maker, not the innocent list admin or (even
worse) the other subscribers.

Out of interest, where in the mailman code does this test get done?
