[Mailman-Users] Diagnosing Uncaught bounce notification

[Ron Crump]

Hi,

One member of one of our mailing lists is continually
resulting in an Uncaught bounce notification when he
mails to the list.

The same address is working fine subscribed to a
second list (which has a smaller membership, a subset
of the main list).

I've never really understood the Uncaught bounce
notification messages, and am hoping to get some guidance
on how to diagnose and address the problem.

Cheers,
Ron Crump.
