Mailman sends mail from LISTNAME-bounces at ...
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-bounces at ... 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.
