dovecot - Aug 2009 - alias does not work

Hi,

Thank you to everyone who helped me get near the goal. Remains a problem
is that aliases don't work.

The problem is that in the configuration of alternc, the mails are seen
as aliases in the form user_domain.tld. In a second time, a match is
made to see if an "real" alias exists.

postmap -q test at lists.test.net mysql:/etc/postfix/mydomain.cf
test-owner_lists.collectifs.net

postmap -q test-owner_lists.test.net mysql:/etc/postfix/myalias.cf
"| /var/lib/mailman/mail/mailman owner test"

With my configuration, this second part doesn't work. Perhaps the
simplest is to ask to deliver the mail to user_domain.tld except of
user at domain.tld in master.cf ?

Thanks
Denis
