You don't need RPC for DNS look up and name resolution. Are you able to do a
nslookup and lookup for the failing domain name MX records ?

I am having a problem where email to certain domains is failing with the error
"Domain does not exist". Now, we are able to send this mail from an outside
source, i.e. hotmail, with no problem. In my firewall, there is an error about
packets getting dropped that coincide with the email errors. The Firewall is
reporting "Packets dropped: RPC Mapper". So, what's the deal? Do I need to
have Port 135 open through my firewall for the RPC? Any ideas?
