Yahoo mail admin

[Steve Teti]

Is there a Yahoo mail admin on the list who could help me?  We had a 
problem with the DNS for our domain a couple of days ago (somehow 
authoritative nameservers were changed at Network Solutions).  Some 
Yahoo users are still unable to send mail to users @monmouth.com, and 
some Yahoo users are sending fine.  The problem is definitely affecting 
Verizon/Yahoo mail users but may be affecting others as well.  I have a 
ticket open but it doesn't seem to be going anywhere.

Thanks,
Steve
