[Mailman-Users] Mailman, Postfix and MySQL-based virtual domains

[Werner Schalk]

Hi,

first of all I have to say that I am a complete novice to both Mailman and 
Postfix. However my MySQL-based Postfix setup works just fine (on Gentoo) but 
I have a problem with getting Mailman to work. Beside virtual domains and 
users that work just fine, I created some mailing lists. But when I try to 
send a mail to one of them I get the following error message in my log file:

NOQUEUE: reject: RCPT from unknown[62.8.A.B]: 550 <testlist at domain.tld>: 
Recipient address rejected: User unknown in virtual mailbox table; 
from=<me at domain.tld> to=<testlist at domain.tld> proto=ESMTP 
helo=<mysystem.network.localnet>
Jan 25 22:52:54 myserver postfix/smtpd[6906]: > unknown[62.8.A.B]: 550 
<testlist at domain.tld>: Recipient address rejected: User unknown in virtual 
mailbox table

My Postfix config file is as follows (digest):

owner_request_special = no
recipient_delimiter = +

virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf, 
hash:/usr/local/mailman/data/virtual-mailman
virtual_gid_maps = static:211
virtual_mailbox_base = /home/virtmail
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_transport = virtual
virtual_uid_maps = static:211

So according to http://www.list.org/mailman-install/postfix-virtual.html and 
what I have found on the web, Postfix should consult 
both /etc/postfix/mysql_virtual_alias_maps.cf 
and /usr/local/mailman/data/virtual-mailman in order to handle the mail (the 
*.db file does exist in /usr/local/mailman/data/virtual-mailman.db). 

However as one can see above, Postfix is unable to find the user in the 
virtual mailbox table. Does somebody have a similar setup and is able to give 
me some information or hints on how to solve this problem? I searched the web 
already but I didn't find anything useful so far. Any ideas?

Thanks a lot.

Best regards,
Werner.
