ARGH! response to localhost, no response to remote hosts

[Mark Drummond]

I'm stumped ... can someone try doing an nslookup against
dev.newzletter.com? Sitting on the master DNS server I can nslookup and
it returns the right answer ... but from a remote location the lookup
times out with "no such host ...".

Yet I can look up www.newzletter.com just fine from either location.
