Exchange server 2003

just setting up a Windows Small business server 2003 which incluses MS Exchange 2003, what I am haveing difficulty with is Exchange 2003.

I have attempted to configure exchange to collect the pop email from BTconnect.com but no at all sure I have even been looking the right place.

The company owns a domain name of xxxxx.co.uk now I believe that the domain name host can forward the email to my server which has a static IP.

How do I configure exchange for both the above.

ALSO

We have a 2nd domain bbbbb.co.uk can this be cinfigured on the same server this email only need to be send to 1 user.

I do hope you are able to assist as I am bashing me head again a wall trying to figure this out
