About PTR records about-ptr-records
A pointer record (PTR) is a type of Domain Name System (DNS) record that provides the domain name linked to an IP address.
With PTR records, receiving mail servers can check the authenticity of sending mail servers by identifying whether their IP addresses correspond to the names that the servers connect to.
