Mailman sends mail from listname-boun...@...

DSNs are returned by foreign (in some cases) MTAs to that address. Spam
is also sent to that address. Since a valid DSN can come from
anywhere, your suggestion doesn't seem viable.

Note however, that a valid DSN should have a null envelope sender and
possibly only delivering mail to listname-boun...@... if the envelope
sender is null might help, but the OP's issue was that some
unrecognized bounces were legitimate bounces, and since to be
unrecognized, they must be non-compliant in the first place, there's
no guarantee they would have a null envelope sender.
