I've been running a Zimbra email server for years now but I want to move it inside our Sonicwall. I have read and researched the wiki's and forums for hours and even tried it on a test server and just can't seem to get a grasp on split-dns.
does anyone have a "split-dns guide for dummies"?
Zimbra 7.1.3 GA 64bit
Ubuntu 10.04 LTS 64bit
DNS is hosted at godaddy.com
