The output of 'postconf -n' and all of the postfix log entries relating
to delivery of a message from Mailman to Postfix.

Possibly Mailman's 'smtp' and 'smtp-failure' log entries and the
contents of Postfix master.cf and other files referenced from main.cf.

If I had to guess, my guess would be that 'localhost' or it's equivalent
IP (possibly IPv6 - see /etc/hosts) is not in Postfix mynetworks in
main.cf and the resultant issue is 'relay access denied'.
