[Exim] domainlist.

I have a problem relaying mail to my exchane server located inside a
firewall. The Exchange server has internal IP address. I have installed
exim 3.32 on Sun box (solaris 8) . The Sun box acts as a relay. The
problem is that mail is not get routed to the firewall. I assume its
because the lowest mx record is pointing to the relay. The domailist
routing is just not working. What could be the problem.
