Probably becuase the DNS is failing - contact the operators of the
primary DNS and have them check their setup. Two things in particular
to check, often I have seen a zonefile that left out the priority of
the MX cause DNS to fail, and also putting an IP address instead of a
hostname (an MX has to point to a HOST *NAME*, not an IP)
