How do you update PTR Records
Posted on 2007-10-02
I'm managing an in-house exchange server which ran solely off of a business class DSL line. Recently, we added a T1 connection to the network and setup load balancing between the two lines for automatic fail over and better throughput. The issue now is that since our email server is now sending out emails over two IPs instead of just one, some ISPs have started to flag our second (t1) IP address and a possible spammer/abuse IP. I'm fairly certain that this is a PTR issue (correct me if I'm wrong) but I'm not entirely sure how to update our records in a manner that says both of these IPs belong to our company and our exchange server and emails from them are OK. We have one exchange server and two DNS servers; all running on windows 2003.
