How can we configure Additional Domain for Exchange Mail User and Mail flow should be inside the organization?
Actually, i have a domain named: "haku.com" and it is used for internal and external mail flow in an organization. Now again i need to create a additional domain like suppose : cmail.haku.com for exchange mail user and mail should be flow inside organizations only.
Example: "binod@haku.com" is already created mailbox user and this user can sent and received mail from inside and outside the organization to all. But now we need to add such domain like: binod@cmail.haku.com and this user can sent mail inside the organization to all. How can we configure it??

As Michael said, you first create an internal DNS entry for the subdomain in DNS ... the subdomain is like an alias that you name "cmail" under the "haku.com" DNS zone. If you use Windows Server to do your DNS, open the DNS console (or open the MMC and add the DNS snap-in) and connect to one of your DNS servers to set that up. You would point it to the internal IP address or name of your exchange server and then on the exchange server itself you ask exchange to listen for that subdomain. But you do have to create the subdomain first. Many exchange configurations already have a subdomain setup in DNS that reads something like "mail.domain.com" or "webmail.domain.com" so go look for one of those in the DNS zone for your domain and if so just look over it as an example and then mimic it's settings in both DNS and exchange. If you don't already have an MX record for a subdomain like that already setup to use as an example, one of us can probably find you a walkthrough for how to set it up. Do you need a "creating an MX record in Windows Server DNS" walk-through? You may not even use Windows Server for your DNS, though so we would need to know that for sure.
