This month the IT staff in the company left our company without any notice. I'm now once again back in trying to resolve some major mail problems. A great number of our companies emails are not reaching hosts such as AOL, Comcast etc... After looking around I suspect a PTR issue and even more I believe our Email server was never setup with proper DNS records. I'm not in anyway ready to figure this out myself so I would like help getting our servers setup with correct DNS and PTR records. I will break down our system design in detail. Currently webmail is enabled under webmail.newerafinance.com as the only method of mail access.
Domain Name is newerafinance.com hosted by 3rd party provider.
1 In house AD Domain Controller setup newerafinance.local 192.168.0.2
1 In house exchange server setup on the same network as DC.
LAN Network is on 192.168.0.10
WAN Network is on 18.104.22.168

Domain is registered and host records are setup with namecheap.com
To view current records please go to http://www.myhostpix.com/namecheap.jpg
Public nslookup with mx records show..
newerafinance.com MX preference = 10, mail exchanger = webmail.newerafiannce.com
newerafinance.com nameserver = dns1.name-services.com
newerafinance.com nameserver = dns2.name-services.com
newerafinance.com nameserver = dns3.name-services.com
newerafinance.com nameserver = dns4.name-services.com
newerafinance.com nameserver = dns5.name-services.com
dns1.name-services.com internet address = 22.214.171.124
dns2.name-services.com internet address = 126.96.36.199
dns3.name-services.com internet address = 188.8.131.52
dns4.name-services.com internet address = 184.108.40.206
dns5.name-services.com internet address = 220.127.116.11
As you see Im not sure where to start looking to resolve the DNS issues and setup PTR but from the looks up things it seems as the network was never finished with proper settings. What I also see as a problem is that the domain newerafinance.com points to the 3rd party host provider but yet the mail server is in house therefore setting up PTRs is not simple for me.
