I need to setup a mail relay to one of our remote offices.  They have a different domain name.  How is this done in exchange?

What do you mean?

You want all mail destined for this other domain to come via your server?

Yes.  they have no servers there.  The mail will route through us, and go to their office.

You need to setup an smtp connector with the IP or servername to the remote box.

OK, if you want to host their mail, then you are not relaying anything (relaying would indicate that they have a server).

You need to configure your server to be responsible for their domain, then you want to configure their machines to pull email directly (preferably using RPC/HTTP)

First you need to setup MX record for the other domain to point to your Exchange server's external IP
Next, you need to configure recipient policy to include the other domain - this will let your Exchange knows that it is responsible for email of the other domain
Then, you need to add users & mailboxes
Finally, you need to figure out how the users of the other domain will get their mail, POP3 or Exchange

how do i setup the recipient policy?  everything else is setup.  what happened was that we took our barracuda firewall offline because it was failing.  every since then, our remote office is not receiving mail from the outside.

the recipient policy is the first link I gave you

If you have a Barracuda box, then most likely the recipient policy is already in place.  When messages sent to the other domain, is there any error messages indicating where the messages go?  Rejected?

You just saved me hours of headaches.  The problem smtp domain was unchecked on the policy.  I'm not sure how or why this happened.  I think they might have been routing it through the Barracuda.......of which is offline at the moment.  Issue resolved.
