[SOLVED] Mulitple domains

[leog21]

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

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.
