      Start with DNS for anything like this. Figure out how each server will look up the other.

      Second, look at the error messages and see why it says that it was not sent.

        This is the mail system at host mail.yourmail.studio.
        I'm sorry to have to inform you that your message could not
        be delivered to one or more recipients. It's attached below.
        For further assistance, please send mail to postmaster.
        If you do so, please include this problem report. You can
        delete your own text from the attached returned message.
        The mail system
        nagendra@yourmail.com: Host or domain name not found. Name service error for
        name=yourmail.com type=A: Host found but no data record of requested type

          name=yourmail.com type=A: Host found but no data record of requested type

          Right, so there is your answer. Host or domain name not found. The sending system has not record for the receiving system, it has no idea where to send the mail. So DNS is the problem.

              Email is unidirectional. The ability to receive tells you nothing about the ability to send.

                    Those DNS responses are quite different. Is one coming back from the DNS servers publicly and one from the local DNS?

                        And the info that it is returning is the correct name of the email server?

                            Then you need to go into your AD DNS server and change it so that it is correct.

                              hange it so that it is correct.

                              in AD DNS everything is correct

                                So DNS lookups are correct now?

                                    There are only so many possibilities..... if you get the wrong answer from DNS, then DNS is wrong. DNS needs to be corrected. Either you need to look to the right server for resolution, or you need to change what is in that DNS.
