MX records and Nslookup

[Brian Salomaki]

Hmm...call me crazy, but you might want to change your secret :)

Usually, it's accepted practice to obscure your secret, since that's private 
information, but to give us the domain names, since DNS information is 
inherently public.  If we try to look at your problem, and run queries 
against ns1.seconddomain.com, we probably won't be able to help you, since 
you obscured it.  Please give us some real domain names, and generate a new 
rndc key.
