I have a list named "supt" with 252 members that received an email that only went out to 1 recipient. After looking at the mailman smtp logs, I am seeing a number of lists that are only sending to a single recipient but have dozens to hundreds of members. Nothing is showing up in the "post" log for these problem lists. How do I troubleshoot this deeper? I still have many lists that seem to be working properly and actually have entries in the post log.

What does
list_members -r -n enabled supt | wc -l
show? If it shows more than 1, is there anything in the list's Non-digest options -> regular_exclude_lists?
It could be the case that in the above logs, the post was held, discarded or rejected and the one smtp message was a notification. What's in Mailman's vette log for this time?

The regular_exclude_lists field is blank.
The vette log has nothing at this time period. It skips from Oct 10 10:26:50 to 10:42.20.

What's in the Postfix maillog for the above smtp log message? Find the message at that time with from=<supt-bounces... and show all entries with the same Postfix queue id.

This has been resolved. The post was from a non-member and generic_nonmember_action was Reject and the SMTP recipient was the poster being sent the rejection.
Note that generic_nonmember_action = Reject is a bad idea in general because it causes backscatter to innocent 3rd parties with spam with spoofed From: headers.
The fact that these rejects aren't logged is a bug <https://bugs.launchpad.net/mailman/+bug/1068837> and will be fixed.
