Mysterious Named Log Message

[Jim Logan]

I keep getting the message, "named[1633]: ns_resp:
query(pop.east.cox.net) No possible A RRs."  When I run dig or host
manually with that domain name I don't get that message.  I even did it
in a tight loop for a while.  What could be causing it?  It seems to
happen as a result of fetchmail polling my POP account every 15 seconds.

Earlier I was getting a "possible loop" warning until I commented out
the following lines:

     #       forward first;
     #       forwarders {
     #               68.100.16.25;
     #               68.100.16.30;
     #       };

Any ideas?

Thanks,
-Jim
