Thanks to Sean I've made some progress. It seems that local users on lists.host.org server can receive and send emails. Mailman on lists.host.org can also receive emails. However, there is an an error message when Mailman tries to send email out to list subscribers. The error message I see in the logs is "Unrouteable address" for each email address in the list (e.g. em...@yahoo.com). ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org
