What is FCrDNS?

Forward Confirmed Reverse DNS FCrDNS is a DNS technical configuration that shows a relationship exists between an IP address and a hostname. By having FCrDNS, you prove that your IP address is using a sending domain that you own. This relationship provides a form of authentication that some mailbox providers use in their spam filter methodology.
