      hi guys,

      i have a problem that my kopano / postfix on ubuntu 18.04 doesn’t send mails to my own domain.

      My domain is for example: test.com

      I try to send a mail from admin@test.com to admin2@test.com
      there comes the following error:

          i apologise, the error is indeed something other than the linked post. Reopened.

          Edit: but maybe a similar solution?

          @nils50122 said in Kopano / Postfix doesn't send mails:

          Jun 19 07:40:36 exchange postfix/lmtp[17761]: connect to localhost[127.0.0.1]:2003: Connection refused

          has the dagent started?

            telnet 127.0.0.1 2003 and telnet ::1 2003

                Looks like the Kopano-Dagent can’t start.

                I set the log-level from dagent to 6.

                With default dagent.cfg there comes the following error:

                Thu Jun 28 11:44:18 2018: [info   ] Maximum LMTP threads set to 20
                Thu Jun 28 11:44:18 2018: [crit   ] Unable to create socket(2,1,6) port 2003: Address already in use
                

                When i adjust the dagent.cfg to:

                lmtp_listen = [::1]:2003 127.0.0.1:2003
                lmtp_port = ""
                

                there comes no error in dagent.log, but the service can’t start again.

                Thu Jun 28 12:01:40 2018: [warning] Config warning: Option "lmtp_port" is recognized but obsolete, and will be removed in a future release.

                    You have to remove lmtp_port = "" from your config, as it overrides lmtp_listen.

                    In fact you don’t need either of those as dagent will listen on :::2003 by default (all ipv4 and ipv6 addresses)

                      Neither overrides the other.
                      But "" is a silly value - it is not a valid integer and it is also not the empty value.
