Hi. I'm trying to configure Mailman and I just fell on this as well.
I want to use dedicated virtual subdomains like @lists.virtual_dom_1.tld @lists.virtual_dom_2.tld and I thought following the advices in files /usr/share/doc/mailman/README.Debian /etc/mailman/postfix-to-mailman.py would lead me to it, as it reads ---------------------------------- Postfix ------- For those using postfix who are able to devote a full subdomain lists.example.com for use by Mailman, please see the comments in /etc/mailman/postfix-to-mailman.py . ---------------------------------- IIUC, this method is broken. I guess I'll have to find my way through Postfix/Mailman configuration. Maybe those files ought to be updated to remove (or better, fix) the instructions they provide. Thanks. -- Jérôme
