  • Google servers will reject  bulk email from IP addresses with no reverse name
    Make sure that you Keep valid reverse DNS records for the IP address(es) from which you send mail, pointing to your domain.

  • Hi,

    PTR record is essential because lots of organization do reverse lookup. If you don't have it, you stand a very high chance that email from your domain is rejected by some external party.

    PTR (pointer) Creates a pointer that maps an IP address to a host name for reverse lookups. Please refer to the following article to create PTR record:
