Description: Number of spam emails by Reverse DNS
What is msSpamControlsRDNS?
This counts spam emails caught because the sending IP lacked a valid reverse-DNS (PTR) record matching its claimed hostname. Because many small legitimate mail servers also lack proper PTR records, a high count here carries a real false-positive risk and is worth spot-checking before treating it purely as an attack indicator. For example, 60 messages might be flagged for missing PTR records, several of which could be from a legitimate small vendor's misconfigured mail server.
