exchange server 2003 w/ external dns & SSL
My main goal is to access exchange server with mobile devices and offsite outlook, but let's get the basics together
i have port forwarded udp+tcp, 25 54 80 110 3389
my forward external dns seems to be functioning properly example.com
and my exchange and domain controller are working beautifully too
local dns and domain are domain.example.com and set to send mail as example.com
outlook w/ exchange is working locally and I am able to send and receive e-mail to my gmail
but other places like my @live.com throw it right into spam/junk i'm figuring because of not having SSL and or reverse dns working properly
I realize that hosting your own DNS is insecure I am doing this all for learning purposes!
I have the domain w/ godaddy and they are not even doing the dns hosting, I have nameserver set to ns0.example.com
i have the zone for example.com with nameserver ns0.example.com pointing to the external IP address and obviously mx record for hte FQDN ns0.domain.example.com
I created the primary reverse zone with the first 3 sections of IP address and proceeded to set a ptr for the fqdn/host and enter in the correct 4th digit section of the ip address from what i've read i have done this correctly
I read somewhere you have to call your ISP for them to set you up with the reverse dns which for me is Qwest (i already have a static ip obviously)
if this is true should for this exchange situation do I just ask qwest to setup reverse dns for example.com and nothing else? I don't want to call them without knowing exactly what I need to do

OK - 71.39.214.22 resolves to ns0.example.com
OK - Reverse DNS matches SMTP Banner
0 seconds - Good on Connection time
Not an open relay.

but my Ip address resolves to ns0.example.com (i set this up with qwest) when the exchange is set to send as example.com but is actually domain.example.com
when I run the smtp test @ mxtoolbox.com it says reverse failed still, even though reverse lookup comes up with correct thing I set up, ns0.example.com
here is the error from smtp test for example.com @ mxlookup
a:example.com
smtp:1.2.3.4 (external ip address) smtp
220 ns0.domain.example.com Microsoft ESMTP MAIL Service, Version: 6.0.3790.0 ready at Sat, 2 Apr 2011 16:57:09 -0700
Reverse DNS FAILED! This is a problem.
Do i need to set my PTR with qwest to be ns0.domain.exmaple.com?? please help before tech support closes lol!
