Diagnosing Uncaught bounce notification

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.

I'm guessing you mean that instead of his post going to the list, it results in an uncaught bounce notification to the list owner containing his attempted post.
If that's correct, he's sending his post to the LISTNAME-bounces@... address instead of to LISTNAME@... . He probably has that address in his address book, or perhaps he's replying to posts and using MS Outlook or similar which is replying to the Sender: instead of the From:. See the FAQ at <http://wiki.list.org/x/RoA9>.
Uncaught bounces are messages sent to the LISTNAME-bounces@... address which are not in the standard DSN format nor one of the many non-standard formats which Mailman recognizes.
If they look like real non-delivery notices, they should be posted to this list (mailman-users@python.org) so the recognizers can be updated to recognize them, but often they are just spam or misdirected posts sent to the LISTNAME-bounces@... address.
