It is also possible that the local resolver got corrupted by a name server
that uses * mx records. Reloading or restarting named on your system
and restarting sendmail should clear up the problem. If it comes back,
and nobody has changed /etc/resolv.conf (even if they put it back again)
the problem is on the other end, not yours.
