Your observations are correct and that's the way bounce processing is
designed to work.

If you want to be notified of every bounce, you have a few choices:

1) Be sure bounce_processing is Yes and bounce_notify_owner_on_disable
is Yes, and set bounce_score_threshold <= 1.0. This will cause a
notice to be sent to the list owner containing the bounce message on
the first bounce. The downside is the member's delivery will also be
disabled, and the owner will then need to re-enable it, unless the
address is truly undeliverable.

2) Change the alias for LISTNAME-bounces to deliver to "owner" instead
of "bounces". This will direct all bounces to the owner, but requires
delivery to Mailman to be via alias and to be truly effective requires
aliases to not be automatically generated.

3) Create a cron to run a few times a day and go through the bounce log
looking for entries like

May 28 05:06:04 2009 (12757) LISTNAME: u...@example.com bounce score:
with timestamp > than the last run and mail a notice to LISTNAME-owner.

4) Modify the code to do what you want.
