We want to install 2 exchange server in one single domain. For both exchange servers there is one accepted domain and that's the same for both.
Both exchange servers and domain controllers are in an internal domain with one public ip address.
Incoming email will only be possible from only one domain (ip address) the internet.
What's the best way to appraoch this?
NAT port 25 to one of the servers and let that server relay emails if they are sent to mailboxes on the other server?
Thanks in advance.
