Either you don't have correct entries in the nameserver, or your
/etc/resolv.conf on gc-infra is not using as it's

What is the output of nslookup on gc-infra when you key in
the name?  What is it when you issue
a "set type=mx" at the nslookup prompt followed by the name?  What is it when you key in the
IP number
