It's as if it can't resolve the primary MX and is therefore going for the next 
one, relay-1/ The strange thing is though that it should be 
using the smart host on your internal network rather than going for the MX 
hosts anyway.

Are you sure sendmail is using the right file? ISTR that in old 
versions of Red Hat Linux, was in /etc rather than /etc/mail
