Try checking the Mailman (typically $prefix/logs/) and MTA (typically 
/var/log/mail) logs. Using message-ids to correlate log entries you 
should be able to track an incoming message from the MTA's mail log to

distribution back to the MTA mail log. You may find evidence of 
problems in any of those logs and also in Mailman's smtp-failure, error 
and bounce logs. If you have a copy of a message that made it through 
the system and back out again then the Received: headers will give you
