I've gone through the guide for mailman with some difficulty, but seem to be nearly there. I'm able to navigate to the mailman web GUI, create lists and subscribe. I just subscribe my local FQDN, so [email protected] for testing purposes. This FQDN only works on localhost.

However, e-mails to the list address, in this case [email protected], are rejected:

Why is this e-mail rejected? It seems to, maybe be related to the alias_maps and alias_database settings in postfix.
