It looks like the system having this problem has a serious DNS resolution 
problem.  I wish I could add more, but, if I was you I would be trying to 
find out why your sendmail server can't get the MX RR and associated A RR 
for gamerate.net.

If you can get to a shell, try this:

$dig mx gamerate.net


and see what you get.
