Strange problem resolving yahoo.com

[Jeffrey Keil]

Greetings:

We're running bind on a Macintosh OS X server. There is never any
problem with DNS except for one domain. We have problems with
yahoo.com and no other domain that I am aware of.

As you can see from the output below, we can resolve yahoo.com with
dig and nslookup, but we can't check email at yahoo because we can't
resolve mail.yahoo.com or login.yahoo.com:

~ root at osx2 # nslookup yahoo.com
Server:  ns2.gcs-usa.com
Address:  192.168.1.42

Name:    yahoo.com
Addresses:  66.94.234.13, 216.109.112.135

~ root at osx2 # nslookup mail.yahoo.com
Server:  ns2.gcs-usa.com
Address:  192.168.1.42

*** ns2.gcs-usa.com can't find mail.yahoo.com: Non-existent
host/domain
~ root at osx2 # nslookup login.yahoo.com
Server:  ns2.gcs-usa.com
Address:  192.168.1.42

*** ns2.gcs-usa.com can't find login.yahoo.com: Non-existent
host/domain

This is a problem that is getting worse. I can't even pull up yahoo's
web site in a browser now. I'm not sure what the problem is. Any help
or suggestions would be greatly appreciatedly.

Thanks,
Jeff
