I'm not sure what the issue is. Do these bad addresses never get removed
because you are continuously removing and re-adding them, thus resetting
their bounce score every day? Or do you just want to see the 'first'
bounce from a new member so you can delete that address faster than
normal bounce processing does?
You are correct about what Mailman does. The only actual bounce DSN that
is not simply discarded after processing is the one that caused the
score to reach threshold and disables delivery. That one is sent to the
list owner with the disable notice if bounce_notify_owner_on_disable is Yes.
If the problem is that bad addresses are never getting disabled and
removed because you are continuously rebuilding the list and resetting
scores, you could try using bin/sync_members to update the list from the
HR data. This will not reset scores or options for existing members.
If that is not the issue, and you just want to see the first bounce for
a new member, and you don't want to do this in the MTA and you don't
want to modify Mailman code, the only way is to set
bounce_score_threshold to 1.0 or less so that everyone is disabled on
the first bounce and then re-enable those that shouldn't be disabled
