I am wondering how i can set up zimbra domains and subdomains. I have named my zimbra server mx1.canmail.org and have a webpage running on another server at canmail.org and www.canmail.org using DNS. My question is how do i make zimbra accept logins in the form user@canmail.org rather than user@mx1.canmail.org. When i try to add the domain canmail.org nothing happens completely differnt domains add as normal.
