[Mailman-Users] listname at lists.domain does not work, listname at domain does

Wed Nov 11 01:16:37 EST 2015

Hi Mailman community,

I am using postfix with dovecot on a Debian server. I followed <
http://wiki.list.org/x/ZoCj> for setting up mailman, but something is wrong
with my postfix configuration.

I can create new lists on http://lists.mydomain and when subscribing I get
the subscription notification from mailman. But for sending to the list, I
have to use listname at domain instead of listname at lists.domain. Mails sent to
listname at lists.domain just seems to get lost(don't bounce or end up in
/var/log/mail.log)
I am sorry so disturb with such a question, but I am really stuck.

This is the full log when sending a mail to test at mydomain. The mail is
being delivered to local user tester's inbox.

There are no errors in relevant postfix/mailman logs.
I do not use postfix-to-mailman.py.

What have I done wrong with the postfix configuration? And where does the
listname at list.domain maills go?
