[Exim] multiple domains and mailboxes

Dear all,

I'm relatively new to exim, I have a server which holds multiple domains. I need to be able to recieve email to users at these domains.

eg: paul@??? and paul@??? where both domains are held on the same server although are two completely different mail boxes.

Is this possible with exim? can someone point me in the right direction?

Thanks in advance,

Paul
