I have a problem with one of my servers,
Suddenly i am getting a lot of "Deferred: Name server: xxx.xxx.xxx: host name lookup failure" while DNS resolving on that box is ok(from the command line de backend servers do resolve and are reachable). The mail stays in the mailqueue.
That's normal when a spam-run drops a lot of mail in the queue before someone at the registrar yanks the DNS registration. You can manually flush the queue with a shorter or zero retry interval to clean up the queue of this stuck mail via sendmail -q....
