      @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

                @dbeato said in Zimbra help..multi-domain each with own external relay:

                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.

                    @dbeato thanks!

                    Do I also need to include both SMTP servers in MTA Trusted Networks? How do I input them in CIDR format?

                    119.93.x.x /32?
                    119.93.x.y /32?

                    Thanks!

                      Yes /32 is one IP address.

                          Yup...tried to enter the IPs in MTA Trusted Networks but still the same even after issuing "zmcontrol restart" and even restarting the whole VM. It seems as though that the email is being sent directly to the recipient's server (Google's in this case):

                            Yup...tried to enter the IPs in MTA Trusted Networks but still the same even after issuing "zmcontrol restart" and even restarting the whole VM. It seems as though that the email is being sent directly to the recipient's server (Google's in this case):

                            Can you setup a relay as below?

                              Thanks @dbeato, by goal is to use our own SMTP (external email server) as smarthost. We are using the 2 now, in a separate physical Zimbra installation, without issues. I was only trying to replicate that settings into a single (VM) zimbra install.

                              Thanks again for sticking with me to help me out with my dilemma.

                                Strange, I mean your error seem to be trying to connect to Gmail that the ports are timing out.

                                  That's where I'm also confused about. It seems that it is directly trying to connect to Gmail to send the messages. The recipient is my personal gmail account. Creating bysender and relay_password files and configuring Zimbra to recognize those (by the searches I had done), it should have routed the mails to the external (SMTP) server.

                                  Inputting the smtp.domain1.com to "Relay MTA for external delivery" routes all outgoing emails to it, including the ones from domain2.com which should route to smtp.domain2.com.

                                    Guys, I'll be out and will be back on Monday. Tomorrow is a holiday here in Philippines, work resumes on Monday. Hope you can help me out :smiling_face_with_open_mouth:

                                    Thanks!

                                            @BBigford yeah, that's it. And no fault of any other. I just can't figure this thing out...luckily, its just a test server (planning for an upgrade...thus the test).
