I am currently installing a second exchange server in a domain. The MX records at the ISP they are going to put both the servers. Lets say server 1 and server 2. What i would like to know is what happens when the mail comes to server 1 for a user whose mailbox is in server 2. Will server 1 boucnce it back to the sender saying no email address exists or does it route to the server where the mailbox exists?
Do I need to configure any connectors between the servers? I currently want both the servers to speak to the ISP directly.
Thanks and Regards
