Your subject appears to be an imperfect match to the need you describe.
What you are asking for in message body is a means to discard bounces
*received*. The Subject covers bounces you would *generate*, hence the
'errors_to' suggestion.
But it appears you need both, s.b.

The odd DSN now and again will come back. But relay or otherwise, nothing on
your input side should be generating traffic that gives rise to either large
percentages or large absolute numbers of undeliverables *as 'repeaters'*.
Mailing Lists are the most common scenario where these DO arise, and MLM's
*need* to see DSN's to automagically clean their lists.
IF MLM's are NOT in your scenario, one does wonder WTH you are supporting that
gets an invalid address even ONCE ,let alone repetitively (over quota already
discussed...)
But if you must ....
Look for...
Return-path: <>
...and route according to your needs.
A bit more 'intelligence' than just the '<>' is recommended.
