For running a mail server having a proper reverse resolution is no must
have. Of course it is recommended, because some providers started to
make that a requirement in the field of fighting nowadays SPAM.

Your argument is true when saying that if the whole line is down and no
server is reachable on your site, what would it help if DNS is still
acting because running at an outside provider. But said that, it is a
must to have at least 2 DNS servers responsible for a domain. This is
for fallback. So a fallback MX is up from a certain size a
recommendation too (not a must like with the DNS).

I would suggest: get the DNS and what else services like mail inhouse
and keep Network Solutions as secondary DNS service (you have master
zone control and they are slaves). This is for forward name resolution
as well for reverse. Maybe they offer a fallback MX too. You are then on
the safe side.

And I agree with all of that. The only issue here is that my boss is worse than paranoid. He's one of these 'know enough to be dangerous' geek wannabes and has all these fears and phobias over things. He doesn't like having DNS in house because he didn't have anyone to manage it (except for me now) and like I said earlier he was concerned about domain availability if the T1 went down and DNS was here.

I fully intend on moving to the fedora DNS server here in house as soon as I feel comfortable enough with telling him that that box even exists. He's all M$, and linux makes him nauseous. It's just been a struggle to move forward when 'the man' wants to hold you back out of fear of the unknown.
