    Red face [SOLVED] Mulitple domains

    Can someone direct me to the right post/wiki.

    I am trying to use multiple domains on zimbra.
    I am running Zimbra 4.5.6 on a box behind a firewall via 1-1 NAT using SPLIT DNS.

    I have successfully setup Zimbra to route mail.

    What steps do I need to take to setup additional domains aside from adding a domain in Zimbra? Do my new records need to have HOST records pointing to my original setup domain? or do I simply need to change the MX records for all new domains to that of the original domain?

    Thank you for your help,

    Leo

    Default

    You need a mx record for each. The host A record it looks up should point to the public IP of the Zimbra server.

    For example, you have the following domains in Zimbra:
    zimbraservermail.com
    zimbrausermail.com
    zimbracoolawesomeforums.com

    Then you need an mx record
    zimbraservermail.com would resolve to
    10 mail.myserver.com

    zimbrausermail.com would resolve to
    10 mail.myserver.com

    zimbracoolawesomeforums.com would resolve to
    10 mail.myserver.com

    and a host a record for mail.myserver.com would reflect the PUBLIC Ip of your server.

    all done.
