[Mailman-Users] strange -owner behavior?

[Lucio Crusca]

Hello all,

I've a mailman setup on a Debian lenny system which runs a few mailing lists. 
All seems to work (more or less) except one that does not work at all 
("linux08", but, once upon a time, that one used to work). The MTA is postfix 
backed by a mysql database. The situation:

1. No message seems to go through the list "linux08"
2. Other lists mostly work, but I don't get the messages for the list owner, 
although my email is configured in the relevant field in the control panels
3. The owner address is hosted on the same server where the lists are
4. The same owner address is my usual email address that otherwise does work 
ok.
5. /var/log/mailman/smtp-failure reports continuos failures for every list 
owner, e.g.:


Mar 04 19:42:48 2010 (3140) All recipients refused: {'linux08-
owner at lists.virtual-bit.com': (550, '5.1.1 <linux08-owner at lists.virtual-
bit.com>: Recipient address rejected: User unknown in virtual mailbox 
table')}, msgid: <mailman.126.1267728167.3138.linux08 at lists.virtual-bit.com>
Mar 04 19:42:48 2010 (3140) delivery to linux08-owner at lists.virtual-bit.com 
failed with code 550: 5.1.1 <linux08-owner at lists.virtual-bit.com>: Recipient 
address rejected: User unknown in virtual mailbox table

I understand that mailman is trying to send messages to the address 

linux08-owner at lists.virtual-bit.com

but that address does not exist. The fact is that I do not want it to exist, 
because I've configured my usual email address in the list owner field of the 
list control panel. Why mailman sends to that address instead of mine?

Thanks in advance,
Lucio.
