[Mailman-Users] Analysis of reasons for bounce responses

[Christine De La Rosa]

Thanks for the response JC.  I am checkig with exim and cpanel, to see
if they can at least point me in the right direction.

I checked my smtp-failure log in the mailman directory and are seeing
hundreds of these.

Aug 03 08:01:14 2003 (30019) delivery to non_debutante at xxx.com failed
with code 550: cannot route to sender address
<mailman-bounces at alpha.butch-femme.com>

code 550: cannot route to sender address

Aug 03 08:03:22 2003 (30019) delivery to wolf at xxx.com failed with code
550: cannot route to sender address 

Is this attached to the bounce backs I am getting which usually say 550
REQUESTED ACTION DNS Failure

Thanks for any help in advance

This is a big clue that the MTA is improperly configured and is trying
to 
deliver to the AOL and Hotmail servers messages for more recipients than

those systems allow - triggering anti-spam filtering on the recipient
MTA 
at AOL and Hotmail.  The messages are then bounced.  My guess is that
they 
changed the MTA at around the same time they upgraded Mailman, and you
are 
barking up the wrong tree to try to find the source of the problem.
