Exchange is your first problem. About a year and a half ago I setup some
tests to test the reliabilty of some mail servers. These tests included
all the company mail servers, Exchange, Lotus Notes and IPlanet/Netscapes
Messaging server as well as some free services. The tests showed the most
reliable server was ccil.org running Debian and EXIM. The worst was the
companies own Exchange server. So put another way the one of the most
expensive products the company sold (Exchange $15 per user per month) was
less reliable than the free service provided by ccil.org running free
opensource software.

Thats a matter of taste, I prefer Debian and EXIM.

whois shows your authoritave DNS servers are:
NS1.GRANITECANYON.COM 205.166.226.38
NS2.GRANITECANYON.COM 65.102.83.43
At that messaging company I used to work for one of the clients, a local
University, used the free GRANITECANYON DNS services. It was sad to see
this Univ paying big bucks to outsource their email and every so often the
GRANITECANYON DNS servers would just lose the DNS zone info for that
domain. Or put another non technical way GRANITECANYON DNS servers suck
and when they fuck up you bounce mail.
