It is the process in which an IP address is matched correctly to a domain name instead of its reverse. It is a popular method of catching spammers. Spammers use invalid IP addresses which are detected easily by a reverse DNS. Emails may get rejected if the program or spam filter fails to match the IP address to the domain name.
