I configured a domain server hosting multiple domains.
I followed this tutorial (perfect server)
I bought the ISPConfig3 manual and configured mailman as put right there.
I created some mailing lists and when I try to send a mail to one, I always get a bounce with the following message:
Recipient address rejected: User unknown in virtual mailbox table
Normal email traffic is working okay. mailing lists don't.
I have the following line in my /etc/postfix/transport:
What am I missing? Do I need to have an MX record pointing lists.mydomain.com to my server? I thought I could relay that locally on the server.
Thanks for your thoughts.
