I've been going in circles between mailman and postfix trying to get things working. My current condition is that either mailman is putting incoming mail in the bit bucket or postfix is not sending incoming mail to mailman. According to the postfix forum my mailman configuration is messed up but it was auto generated by the installer. Supposedly these entries should not be in /opt/mailman/mm/var/data/postfix_lmtp or rather transport_maps and/or local_recipient_maps.
# Aliases which are visible only in the @gmail.com domain. lllllllllll@gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-bounces@gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-confirm@gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-join@gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-leave@gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-owner@gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-request@gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-subscribe@gmail.com lmtp:[127.0.0.1]:8024 lllllllllll-unsubscribe@gmail.com lmtp:[127.0.0.1]:8024
And relay_domains shouldn't have this entry either in /opt/mailman/mm/var/data/postfix_domains in relay_domains:
gmail.com gmail.com
Clearly my postfix configuration is messed up but since this was all auto generated I don't know what to do.
