And what's in them. Do they contain a copy of the Delivery Status
Notification. What does it say?

I'm not sure why you're seeing anything if bounce processing is turned
off for the list. Normally, returned bounces are just discarded if
bounce processing is off. Perhaps you're talking about notifications
from when bounce processing was on.

Are you seeing the actual "bounce" notifications that are being
returned? If so, they will tell you why the mail is bouncing. Without
that information, people can only guess.

If you are getting (have gotten) notifications to the list owner from
Mailman, the triggering bounce message should be attached to the
notification.

You could also try adjusting the bounce processing settings. If for
example, you set bounce_score_threshold to 5.0 and
bounce_info_stale_after to 4, then the only people who get disabled
will be those who have five or more bounces with no more than 4 days
between them. It sounds like your "spurious" bounces don't happen that
often, but if you really have a bad address, this should get that as
long as you normally get posts every day or two.
