              @nagendra Zimbra needs just a few things to change the IP address:

              • hostname must match the IP address (check that /etc/hosts is correct, and reports the right name of the zimbra machine)
              • you must have the right IP address in zimbraMtaMyNetworks:
                as zimbra user,
                zmprov ms <yourmailserverfullname> zimbraMtaMyNetworks '127.0.0.1/8 192.168.4.0/16 <otherIPrangesyouneed>'
              • execute as zimbra user
                postfix reload
                and
                postconf mynetworks
                to check that everything is correct.

              If you use an external dns server, make sure it returns the correct results for your changed IP.

                    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.

                        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.

                                            in AD DNS everything is correct
