I do not know, this could be a novoice question.
The situation is bit tricky - I have a 40 user ZCS OS box running perfectly on our companies domain 'example.com'. We are coming up with 2 branch offices with 50 email user at each branch and I need a ZCS installation at each of this locations on the same domain (example.com).
So how to configure the ZCS so that the local mails at the branch office 'A' are delivered locally whereas only the mail to the outside world and branch office 'B' finds its way out??
I have tried split DNS but I guess that is only good for a single server installation. How do we achieve this when the servers are more than one and the domain name is same??
