I'm putting together a Network Edition server at my work. We have a website hosted externally by a third party. Up until now, we were also using that same third party to host our email.
The website and the emails use the same domain name.
How can I set up a custom DNS that will resolve mail queries (IMAP, Outlook Connector, web interface) to the internal IP, but still allow the regular domain name web request to reach the existing external website?
Is it as simple as using mail.domain.com for the Zimbra server, while domain.com will go external? Does anyone have a link to a guide for setting up a DNS server?
I have gone through a crash course in BIND9 while setting up this copy of Network Edition, with Ubuntu 10.04 on VMware ESXi 5.0. Does the DNS server need to run separately in its own VM? I figure it's poor practice to specify the Zimbra server as the DNS server for all of the workstations.
Any help would be appreciated!
