And having DNS administered by Network Solutions does not prevent you from running a DNS server your own. Forward and reverse resolution can be managed by different servers / service agents (companies). 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.
