Is there a manual that can guide me through the configuration for multiple domains? I have one domain that is a production domain, so I can't disrupt it for testing, but I have a second domain which is experimental, so I have complete liberty. When I answered the installation configuration questions, I answered everything as though I were going to immediately deploy to the production domain, so I need to know how to introduce the second domain.
Thanks for the help,
Adding another domain is pretty easy in Zimbra. Try following the instructions here.
