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@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@domain.tld in master.cf ?

Thanks Denis
