Ah, I'll try this. I'm assuming, by this logic, that postfix is
probably seeing too many invalid rcpt's from the one smtp connection
and as a result, gives this error.
Does mailman handle delivery different to a local MTA, rather than
remote machines? I'm curious, because many people's spam filtering
would limit the amount of RCPTS allowed these days to a value much
lower than 500, right?

Ah, so the mailman bounce handler only works if the MTA actually gives
a real error (i.e. "user does not exist"), rather than just screaming
that there's too many rcpt errors?
Probably explains why it wasn't working, then. I knew mailman had
bounce handling, was wondering why it wasn't working.
(Am I on the right track with the above logic, BTW?)

Signature space for rent.
