Sure, but the beauty is that there's almost no way that a broken MTA can
bounce in such a way as to not know where the message went.  Autoresponders,
on the other hand, suck rocks through straws.  So you can afford to handle a
lot more bounces, and implement an ezmlm-like probe when it gets critical,
all in the certianty that you're (a) not bouncing messages to the list
admins that they have to read and (b) if you miss any messages over a long
time you can reset your counter and let the user know what they've missed.
These are 2 really nice ezmlm features...
