Ensure that Bounce processing -> bounce_notify_owner_on_disable is set
to Yes. Then when the user's delivery is disabled, the list owner will
receive a notice with a copy of the bounce DSN.

Or, with Mailman 2.1.19+ you can set
bounce_notify_owner_on_bounce_increment to Yes to get a notice every
time a user's bounce score is incremented.

This info should also be in the mail log if the bounces are reported by
the local MTA, but not if they are reported by a remote MTA. With
Postfix, look for lines with "status=bounce"
