I have a LAN with one WAN IP. Behind the NAT I have on Windows 2003 server with DNS and Exchange. This server handles one domain.
My question is:
Is it possible to setup DNS to handle mail to Zimbra for another domain? I have tried with seting up A-host and MX on the windows-server to point to the zimbra-server. But now luck here. Is it possible to handle this with DNS?
