sender IP must have reverse lookup (DNS PTR) RRS feed

  • Question

  • delivery is failing to some of domains sending our emails.

    I have internal DNS test.local with reverse lookup zones.

    How can I achieve to have internet facing DNS to support PTR records.

    Domain service provider does not support PTR records and I cannot go to that path

    >>How can I achieve to have internet facing DNS to support PTR records.

    You should connect your ISP provider,tell them to add an external PTR record.And  mapping it to your internal IP address and port.

  • ISP cannot do it

    We have our public IP addresses from APNIC
