Search Again: PTR records required? From: Jim Edmondson Date: Wednesday, December 1, 1999 Time: 11:05:00 pm Is it a requirement in the RFCs that DNS records have a associated PTR record and that a reverse lookup be possible? We have our mail server perform a reverse lookup on incoming connections to try and filter SPAM. Works great but is sure seem that a lot of sites do not have a correctly configured DNS. Makes me wonder if it is a recommendation or a requirement. TIA Jim
