      When talking about easier user management and appliances I have to throw my “go to” solution Univention into the pot as well: https://www.univention.com/products/univention-app-center/app-catalog/kopano-core/

      They also have a Fetchmail app so everything can be done from their web ui.

          Hi folks, thanks for your answer…slowly I’m getting closer to the solution.
          The problem is the dagent. I can’t start it. Is there anything to do in the dagent.cfg? Everything was commented out (auskommentiert).

          Maybe I can find out more…

          Same here is there any sample for dagent.cfg?
          @thctlo i’ts always comming back ;=) 2 years are over and nobody has the problem except from me and you had it? How did you fix it?

          /etc/kopano/server.cfg <- I have probably some configuration issues also there.

          For me it looks like that this tutorial is incomplete as always:
          https://www.pc-howto.com/kopano-der-neue-stern-am-groupwarehimmel-teil-1/
          https://www.pc-howto.com/kopano-der-neue-stern-am-groupwarehimmel-teil-2/

          Maybe I’m just to stupid. @martimcfly I go thru your config files by tomorrow.

            If you run kopano-dagent with the parameter -l, it will bind to port 2003 and wait for connections. [-l = listen mode]

            If you start kopano-dagent with a receipient as parameter it will read mail from stdin and then (with proper input which it gets from fetchmail) deliver this single mail to kopano.

            If your log says “Unable to create socket, address already in use”, then you already have a kopano-dagent running in listen mode and you are trying to start another one in listen mode. kopano-dagent cannot run twice in listen mode. But you can of course have it running in listen mode and on demand call it in interactive mode from fetchmail.

            An empty dagent.cfg should be fine.

              Hi Gerald,

              Now I’m more confident with logs and dagent. It looks now fine.

              I think that I have a problem in fetchmailrc:

              #.fetchmailrc
set syslog;
set postmaster "email_from_root_user_i_created_in_kopano";
# set no bouncemail
set no softbounce;
# accounts
poll webXXX.login-XXX.hoststar.ch proto pop3 user webXXXX pass XXXXXXX options ssl smtpaddress localhost forcecr mda usr/sbin/kopano-dagent -s 4

              This is wrong because of “-s” after kopano-dagent. Do I have to use " " in the syntax if yes, only at mda “usr/sbin/kopano-dagent -s 4”?
              Number 4 is because it’s the sql table written number 4 can I use the kopano-login name as well?

              When I use it with the username and quotes " " and I have to use the directory “usr/sbin/kopano-dagent -s username”
              in “bin” I don’t have a kopano-dagent only in “sbin”.
              I always recieve:

              root@svgwma-kopa-02:/home/kopano# tail -f /var/log/mail.log
May 31 07:23:46 svgwma-kopa-02 fetchmail[3703]: 1 message for webXXXX at webXXX.login-XX.hoststar.ch (6722 octets).

              I use the newest Ubuntu server version…

              On the other side Kopano Core Delivery Agent with Debug Mode:
              The only thing I see which is not correct, is the time. Actually I don’t know why.

              EDIT 3:

                This is wrong because of “-s” after kopano-dagent. Do I have to use " " in the syntax if yes, only at mda “usr/sbin/kopano-dagent -s 4”?
                Number 4 is because it’s the sql table written number 4 can I use the kopano-login name as well?

                Ok, I had “the-local-kopano-user-id” in my example. But that did not mean that you need to dig in the MySQL Database and search for a random hidden usernumber. What is meant by this is just the Username in Kopano.
                I don’t know about the new kopano-cli but in kopano-admin this is what is specified as -u and what is listed as Username in kopano-admin -l

                When I use it with the username and quotes " " and I have to use the directory “usr/sbin/kopano-dagent -s username”

                Why no / in front of /usr? Might work depending on where it is run from, but this looks weird and is an unnecessary reason for it to fail.

                in “bin” I don’t have a kopano-dagent only in “sbin”.
                I use the newest Ubuntu server version…

                Yeah, just mentioned it because this could have been different in other distros. But I’m also using Ubuntu and sbin is correct. Easy to check:

                root@myhostname:~# whereis kopano-dagent
kopano-dagent: /usr/sbin/kopano-dagent /usr/share/kopano-dagent /usr/share/man/man8/kopano-dagent.8.gz

                I always recieve:

                May 31 07:23:47 svgwma-kopa-02 fetchmail[3703]: reading message webXXXX@webXXX.login-XX.hoststar.ch:1 of 1 (6722 octets) (log message incomplete) <--- WHY Incomplete??? 
May 31 07:23:47 svgwma-kopa-02 fetchmail[3703]: MDA returned nonzero status 75

                I have no idea. Perhaps remove the -s from the kopano-dagent parameter (this is for silent)
                Instead add -v (verbose) or -vv (even more verbose)!

                Also add verbose flags to fetchmail, Syntax probably the same (-v or -vv for even more verbosity).

                On the other side Kopano Core Delivery Agent with Debug Mode:
                The only thing I see which is not correct, is the time. Actually I don’t know why.

                I think I had this once too in some log… Don’t remember exactly, but check timedatectl if your timezones are correct.

                Output for me is:

                root@somehostname:~# timedatectl

                This looks like the log from the zarafa-dagent in daemon mode. (Parameter -s)
                Not sure if the logs from a manually started zarafa-dagent in non-daemon mode will end up here to. At least nothin in the log you quoted.

                When I want to list all Kopano users I get this:

                root@svgwma-kopa-02:/home/kopano# kopano-cli --list-users
Traceback (most recent call last):
  File "/usr/sbin/kopano-cli", line 3, in <module>

                Something is here wrong with the DB or so…

                Does kopano-admin -l work for you? The error message looks more like you have not installed a required package?

                  I will check if I can update Kopano and test again…

                  EDIT 1:

                  I download via wget the newest kopano-core and then made the package and installed it.
                  This worked fine so far. After the installation the system user on Ubuntu 18.04 had a new Password <- why?

                  Now when I want to login via Webapp I recieve this error:

                  Unknown MAPI Error: MAPI_E_NOT_FOUND

                  When I make this: kopano-admin --create-store hispeed

                  Then I recieve:

                  kopano-admin: relocation error: kopano-admin: symbol _ZN2KC21GetAutoAcceptSettingsEP9IMsgStorePbS2_S2_S2_ version KC_8.6.80 not defined in file libmapi.so.1 with link time reference

                  It’s getting worser from day to day ;=)…

                    Yes yes yes…

                    I don’t believe it I can now recieve. I updated the whole Ubuntu and restartet. Then I had to change something in the config from Kopano. Attachament stored as File (I made there a change earlier). I’m sure I can switch that to database later.
                    Restarting everything and now I can recieve e-mails.

                    Thanks so far for everyone. There are still a few questions open like: why the kopano user gets a new password after update?

                    Now I have to figure out how I can send E-mails… For this I’m going to use postfix.

                    Postfix i’m back in trouble :D! Yes something is wrong in my postfix configuration.

                    Do you have a sample of the postfix configuration?

                        Postfix offers SMTPUTF8 support, kopano LMTP not.
                        Set in postfix smtputf8_enable = no restart postfix and its fixed. ;-)

                          I need to use this two lines or something similar:

                          smtp_sasl_password_maps = hash:/etc/kopano/postfix/sasl_passwd
sender_dependent_relayhost_maps = hash:/etc/kopano/postfix/sender_relay

                          With this config it doesn’t work. Postfix keeps telling me that the user doesn’t exist in Kopano. But I have created a user with this e-mail.

                          Thanks for your ideas…

                            Have you even tried what i did say… :-/

                            Your logs show:
                            host localhost[::1] offers SMTPUTF8 support, but not 8BITMIME

                            kopano-lmtp does NOT support SMTPUTF8 and you mail is rejected.

                            What you see in your logs is correct.

                            https://forum.kopano.io/topic/1262/kopano-smtputf8-support
                            Already reported this some time ago.

                              and about you postfix config. this part needs serious fixing, this is not ok.

                              smtpd_helo_required = yes
smtpd_client_restrictions = permit_mynetworks

smtpd_sender_restrictions = reject_unknown_address

                              I suggest and this is a verified config by the postfix list.
                              i have more but this is a working setup

                              smtpd_delay_reject = yes

                                @thctlo yes this does fix this error if I add this line. But still there are some other issues.

                                @martimcfly I have copied now your configuration. How do I now create the check_recipient_access-allow.map?
                                Where do I define the passwords and login data for my different mail accounts?

                                At the moment I get this error:

                                On the images you see my old Zarafa config, which is running right now. This works fine for me. Maybe there’s a security risk somewhere I don’t know. First I need to create that on Kopano and then I can add security.

                                  I’m still workin on my postfix configuration. I can’t send e-mails I get at the moment this error:

                                  Maybe I have to configure something in the master.cf? I have added there some lines which I have in my Synology set-up. Unfortunately I doesn’t help.

                                    Hey Highspeed,

                                    I’m sorry for my absence. I was much to busy with construction work.

                                    Passwords are checked against Kopanos imap service. For this I use the saslauthd service. Postfix does its login checks saslauthd. You can find the configuration in github, too.

                                    # /etc/sasl/smtpd.conf
pwcheck_method: saslauthd
mech_list: plain login

                                    https://github.com/pietmacom/com-pietma-zarafa-postfixadmin/blob/kopano/doc/pietma/configs/postfix/main.cf

                                    # /etc/postfix/main.cf

# kopano gateway authentification before accepting relay
smtpd_sasl_auth_enable = yes
smtpd_sasl_path = smtpd
broken_sasl_auth_clients = yes

                                    The e-mail adresses (Mailboxes, Aliases) are checked against postifxadmin. Changes to Mailbox accounts are transfered to Kopano by a services which does poll the postfixadmin changelog.

                                    Postifx is configured to check all e-mail adresses against the postfixadmin database. It executes predefined SQL statements…
                                    https://github.com/pietmacom/com-pietma-zarafa-postfixadmin/tree/kopano/doc/example-config/postfix

                                    # /etc/postfix/main.cf

virtual_mailbox_domains = 
    proxy:mysql:/etc/webapps/kopano-postfixadmin/postfix/domain_domain_to_domain.mysql

virtual_mailbox_maps = 
    proxy:mysql:/etc/webapps/kopano-postfixadmin/postfix/mailbox_username_to_username.mysql

virtual_alias_maps = 
    proxy:mysql:/etc/webapps/kopano-postfixadmin/postfix/alias_address_to_goto.mysql,
    proxy:mysql:/etc/webapps/kopano-postfixadmin/postfix/aliasdomain_at-aliasdomain_to_at-targetdomain.mysql

                                    If you like, you could do the address checks directly against the kopano database.

                                    I hope to find the setting for notifcations here.

                                    Marti
