Actually, the cause of this error message is that the reverse DNS lookup
is not resolving the address of the DNS server. Notice that in his
example he lists the DNS server as '1.2.3.4' and the error message says
'*** Can't find server name for address 1.2.3.4: Non-existent
host/domain'. Yes, the DNS server is attempting to do a reverse lookup on
its own address, and that lookup is failing. This is a known issue with
the BIND shipped with RH and has been for some time. The fix is
simple; make sure that the reverse table is accurate and is properly
configured.
