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 
the Mailman post log, then via the Mailman smtp log for the outgoing 
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 
some idea of what happened for that instance of the message at least 
and might offer hints as to your problem.

You can also take a look at the contents of the subdirectories of 
$prefix/qfiles/ This may give you some idea of Mailman's 
"work-in-progress".
