How do you setup for multiple domains, so that Reverse DNS requests work?
Posted on 2011-03-10
We have a hosted exchange system with multiple domains. The domains mx records points to our site. We have a few clients that have email being refused because the Reverse DNS is not correct, it is showing ourselves instead of the hosted domain. How can we setup our environment so that the Reverse DNS requests are valid? We have asked for the receiver to Whitelist us but have not had any luck. Any information would be helpful. Thanks in advance.
