2 domains in one exchange server

[Liviathan]

I have small biz server installed here at the office. So say i have a domain called 1.com and now I want 2.com to be able to email in the exchange server.

How can I configure that..? I've done some reading but i'm not fully convince how it works.

Any tips, links or info would be great.

Thanks.

I think your looking for this spot.

Exchange System Manager > Recipients > Recipient Policies > right click Default Policy > click the tab for Email Adresses (Policy). You should now see your existing email domain listed. You can add your second smtp domain name there. This opens up possiblities of when you send email from the that new domain address that the reverse DNS lookups may not work for the second address, and cause messages to get blocked as spam by some recipients. When you add this domain everyone will now have that domain address in their user account on the server in addition to their original address.
