Check the bounce values for the list.  IIRC, the default value is 5,
so each bounce (max one per day) is counted against a subscriber.
All bounces are processed by the Mailman bounce process, and only
when a subscriber "achieves" a bounce score at or above the set
maximum is the rejection mail sent to the list owner.

When I ran a Mailman server, I checked the bounce scores on all lists
daily so that I would be able to see which subscribers had bounces,
as many of our lists were re-built automatically from external sources.
I used scripts developed by Mark Sapiro, and he referenced them in a
posting earlier today or yesterday.
