[Mailman-Users] Unknown user when using virtual mailboxes

[David Renstrom]

Hi,

I've set up a system with Postfix, Dovecot and Mailman under Fedora. I'm
using MySQL and Postfixadmin to administrate the virtual mailboxes. I'm
unable to get emails delivered to the mailing lists created with Mailman
though. I've added the required strings to alias_maps and virtual_alias_maps
in main.cf of Postfix:

alias_maps = hash:/etc/mailman/aliases, mysq:/etc/postfix/alias_sql.cf
virtual_alias_maps = hash:/etc/mailman/virtual-mailman,
mysql:/etc/postfix/virtual_mailbox.sql.cf

I've created a mailing list called test for my virtual domain mydomain.se
and everything seems to be correct in /etc/mailman/virtual-mailman and
/etc/mailman/aliases.

Example from /etc/mailman/virtual-mailman:
test at mydomain.se	test

Example from /etc/mailman/aliases:
test:	"|/usr/lib/mailman/mail/mailman post test"

I've also added the following string to /etc/mailman/mm_cfg.py:
POSTFIX_STYLE_VIRTUAL_DOMAINS = ['mydomain.se']
add_virtualhost('www.mydomain.se', 'mydomain.se')
MTA = 'Postfix'

Why do I get the "Unknown user" reply from Postfix when sending an email to
test at mydomain.se? What could I have missed? I've tried to Google this
problem but have come up with nothing really useful. Could you please point
me in the right direction?

This is some output from the /var/log/maillog file:
