Hey guys so I have a need for either a secondary Zimbra server OR some other way to restrict users from accessing our current server via the WAN IP that is set for it. I looked around and did not see any easy way to restrict certain users so I've gone ahead and setup another Zimbra server.
I've never set up a Zimbra server before and I've gotten far enough where it has installed and I can login to it via the web. The problem I run into is that it will not send or receive mail. I suspect its because the server is not set to "mail.mydomain.com" but rather "extmail.mydomain.com".
What would be the proper way to set this up?
