We are having Reverse DNS issues.
10.10.0.10 = Exchange Server
Windows 2003 = DNS server internal.
Setup: 1 to 1 NAT
10.10.0.10 smtp --> 22.214.171.124 smtp
Int gi0/2 = 126.96.36.199
Incoming Access Rule:
any --> 188.8.131.52 smtp permit
When we do a WhatismyIp on exchange server it says the IP is 184.108.40.206
It should be 220.127.116.11.
This is causing our email to be rejected from external sites due to reverse dns not returning 218. External people say are email is coming from 217. Comcast says the reverse pointer is setup correctly.
What are we doing wrong?
Thanks for any help you can offer.
