Follow up with the resolution for the sake of anyone searching the archives at
a later date.
The issue turned out to be with qmail, not mailman. I had the following line
in my tcp.smtp.cdb file:
The correct line is:
Notice the period after the 127. It tells qmail that the 127 is a wildcard.
Without the period, it's taken as an exact match. This prevented any mail
generated on the server from being sent outside the domain, but allowed mail
coming from another authorized relay IP to get through.
