Hi, me again ...
In an older thread I found this regarding external DNS servers (not running it on the Zimbra server)
Now, is this still (Zimbra 8.x) valid, and where do I point Zimbra to an external DNS server? Someone point to the relevant doc (if available).Quote:
You do not necessarily have to run BIND on your Zimbra server to get it working, but you do have to have DNS working properly.
