      (a good practice, anyway.)

      will bug u again please next week once i show this to my management...

      You are lucky that I had to build a new one of these just a few weeks ago that is used in production that I can look at live to help. It has been a while since I had these in production. I like Zimbra a lot, though. It's a good product and works well. And free is hard to beat.

          In addition to the web interface, there is a Zimbra Desktop Client that you can use. I do not use it as it uses Java and that's just silly. But it is an option.

            It's an email server, its main function is to send email. So unless you have port 25 blocked for outbound traffic, yes, it will make an attempt to send emails if you try.

                Now you know that you have that functionality down the road when you are ready.

                      @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?
