          @SAM
          Thanks. Presently, we have an almost similar setup (in terms of relay/smart host but both is on different physical machine and sending to each other means to send or route to our external server.

          Just so you know @SAM is not @scottalanmiller, although Scott does go by SAM. It's just not his username.

            That would confuse even me.

                      Sorry, I haven't been able to connect to that Zimbra server... I am wondering why. Let me report back.

                          There is nothing wrong with what you setup and I have that file on my Zimbra server so I am not sure what is different from yours.

                            I also think so...but setups are stating otherwise. I think I have the local bind9 working as dig works and the first domain is working fine.

                              So you are doing split DNS correct? If so, you need to add that domain there as well.

                                @dbeato No, not doing split dns (well, I just don't get an idea of splitdns so I was thinking it was not implemented). Just simple bind9 implementation making sure it recognize itself as postoffice.domain1.com and itself and the other mail servers (external1.com and external2.com) as mx.

                                • nxlookup and dig is working as expected and seeing itself, including the mx records.

                                • Domain in network is still domain.local.

                                • /etc/hostname is postoffice.domain1.com

                                • /etc/hosts:
                                  127.0.0.1
                                  192.168.0.1 postoffice.domain1.com postoffice
                                  119.93.x.x smtp.external1.com smtp

                                  Seemed like I had given the wrong information, sorry for the confusion. Just occurred to me that I may have provided the wrong info. Domain1.com is also external1.com (same domain name as our external provider). I think it may have no effect but it may have otherwise.

                                  Lets I’ll step back and start my installation procedure. Most of the steps I made are taken from https://ubuntuforums.org/showthread.php?t=1866784 specially those pre-Zimbra installation – preparation and DNS. I think it is the same guide my predecessor has made to create our present server.

                                  Just to make it clear, I have removed the extenal1.com (it is confusing, I think):
                                  Internal network/domain name: domain.local
                                  Server name: postoffice.domain1.com (192.168.0.1)
                                  Zimbra domain1: domain1.com
                                  Zimbra domain2: domain2.com
                                  External server1: smtp.domain1.com (119.93.x.x)
                                  External server2: smtp.domain2.com (119.93.x.y)

                                    Other configuration would be the same as the original post except the external1.com which should have been smtp.domain1.com and external2.com which should be smtp.domain2.com.

                                    Again, thanks in advance.

                                      Okay, so I reviewed finally that Zimbra server. What I found out is that we have three domains in there, one is sending through the WAN IP of the Server as NAT through the firewall while the other two domains are sending through a relay server as below:
                                      0_1518291530281_DeepinScreenshot_select-area_20180210143842.png

                                        Also are you SMTP Servers also on the MTA Trusted networks?

                                          Thanks @dbeato, great! Same as what I'm trying to achieve!

                                          I have below as my settings

                                          bysender:
                                          @domain1.com [ smtp.domain1.com]:587
                                          @domain2.com [ smtp.domain2.com]:587

                                          relay_password:
                                          [smtp.domain1.com]:587 [email protected]:Password1
                                          [smtp.domain2.com]:587 [email protected]:Password2

                                          No. Does it need to be?

                                          Below are mynetworks (edited the line '# name postoffice.domain1.com as it formats large):
                                          zimbra@postoffice:~$ postconf mynetworks
                                          mynetworks = 127.0.0.0/8 [::1]/128 192.168.0.0/24
                                          zimbra@postoffice:~$ zmprov gs postoffice.domain1.com zimbraMtaMyNetworks
                                          '# name postoffice.domain1.com
                                          zimbraMtaMyNetworks: 127.0.0.0/8 [::1]/128 192.168.0.0/24

                                          Honestly, I do not understand the MTA Trusted networks. Our present servers (physical and one domain on one server..this is not the one I opened in this thread) only have the loopback (127.0.0.1/8) and its network (192.168.0.0/24) but our other VLANs, other offices (via IPSEC) and outside access (NATted) works.

                                          What I was thinking is that the since our users are accessing the (zimbra) webmail, it is using the server's own IP address. However, this is also true if I set up POP/IMAP through a client, it connects and sends via the server's IP. Pls. correct me if I'm understanding it wrong.

                                            Your understanding is correct.
