Well, for ourdomain.net, which is one of 5 files for 3 subdomains our
DNS handles, the file contains one MX record as follows:

*      IN   MX   10    Mail

And then of course all the A records, like so...

doodah       IN    A     xxx.xxx.xxx.xxx

and so on...

So to be honest, I'm not sure where it points unless to the obvious, the
machine named mail.ourdomain.net.

When mail is sent to the domain (user at ourdomain.net), the sending server
barfs with "Host unknown".

Thanks again for any assistance.  We have someone else reading
O'Reilly's DNS & BIND whose authors I see frequently posting here.   Is
the answer in the book perhaps?
