      Hello!
      Help me please with problem circular mails via distribution groups. I’ve installed kopano on Ubuntu 20.04 with postfix. Connected to AD.

      kopano-server-packages: 11.0.1.101.66a6a5219-0+584.1
kopano-webapp: 6.0.0.22+2006.1
z-push-kopano: 2.6.2+0-0

      When someone sends email to distribution group postfix sets them into queue for delivering and gets following error:

      May 17 10:34:42 srv-cl-mail-be1 postfix/lmtp[1700746]: 97B9513E5D2: to=<email1@example.com>, orig_to=<group@example.com>, relay=127.0.0.1[127.0.0.1]:2003, delay=7118, delays=6492/9.1/2/614, dsn=4.4.2, status=deferred (conversation with 127.0.0.1[127.0.0.1] timed out while sending end of data -- message may be sent more than once)
May 17 10:34:42 srv-cl-mail-be1 postfix/lmtp[1700746]: 97B9513E5D2: to=<email2@example.com>, orig_to=<group@example.com>, relay=127.0.0.1[127.0.0.1]:2003, delay=7118, delays=6492/9.1/2/614, dsn=4.4.2, status=deferred (conversation with 127.0.0.1[127.0.0.1] timed out while sending end of data -- message may be sent more than once)
May 17 10:34:42 srv-cl-mail-be1 postfix/lmtp[1700746]: 97B9513E5D2: to=<email3@example.com>, orig_to=<group@example.com>, relay=127.0.0.1[127.0.0.1]:2003, delay=7118, delays=6492/9.1/2/614, dsn=4.4.2, status=deferred (conversation with 127.0.0.1[127.0.0.1] timed out while sending end of data -- message may be sent more than once)

      Users receive this mail multiple times. Deleting duplicated messages from queue and restart kopano-dagent fix the problem. Until new message to distribution group.
      I found similar old post https://forum.kopano.io/topic/805/circular-mail-will-be-send-dublicated, but not the same and without solution.
      dagent config:

      lmtp_listen = *:2003
log_method = file
log_level = 6
log_file = /var/log/kopano/dagent.log

      Postfix:

      virtual_mailbox_domains = example.com
virtual_mailbox_maps = ldap:/etc/postfix/ldap-users.cf
virtual_transport = lmtp:127.0.0.1:2003
virtual_alias_maps = ldap:/etc/postfix/ldap-groups.cf hash:/etc/postfix/aliases hash:/etc/postfix/rule_forward_email hash:/etc/postfix/domains

      How can I fix it? Is there dagent bug?

      Also found in dagent.log when problem occurs:

      2021-05-17T08:47:31.633746: [kopano-dagent|T1672773] [error  ] LMTP write error: network error (80040115)

        @bbc said in dagent problem:

        lmtp_listen = *:2003

        Did you already try this with lmtp_listen = 127.0.0.1:2003 ?

          @externa1 No, i did’nt. All works well exept sending to distibution groups. Tried configured

          lmtp_listen = 127.0.0.1:2003

          and restarted dagent. Whait for users action.

          I’ve measured how fast postfix gets group memebers emails (about 100):

          time postmap -q group@example.com ldap:/etc/postfix/ldap-groups.cf
real    0m9,839s
user    0m0,023s
sys     0m0,023s

          It is not critical I think. All emails are valid.

            Hi @bbc,

            you said that you raised logging of kopano-dagent to 6, but did not provide any logging from the service in question (apart from the network error). Are there any other messages in the logs?

            Generally speaking its the job of the mta to resolve your group and then pass the message along for the individual recipients to dagent.

            Regarding

            @bbc said in dagent problem:

            group memebers emails (about 100)

            and

            @bbc said in dagent problem:

            kopano-server-packages: 11.0.1.101.66a6a5219-0+584.1

            I would not really recommend to use the nightly builds for production setups. Packages that have completed testing are available for customers with a valid subscription. If you are still testing out Kopano the recommendation is to request a trial key from https://kopano.com/downloads-demo/ instead of using the nightlies.

              Delivering works well. I noticed today, dagent delivers about 1 email from maling list in 2-3 seconds. It just not finished when postfix sent new equal email to user list. It looks like send timeout in postfix.
              Is there way to speed up dagent? Rise number of threads to deliver?

              @fbartels said in dagent problem:

              I would not really recommend to use the nightly builds for production setups. Packages that have completed testing are available for customers with a valid subscription. If you are still testing out Kopano the recommendation is to request a trial key from https://kopano.com/downloads-demo/ instead of using the nightlies.

              I’ll try, thank you. There is some user data to transfer. And it is a problem. Out of the scoupe of this topic :)

                I had a look at your logging, but did not really manage to spot an error. But 2-3 seconds per mail sounds like an underperforming database.

                There is however a way to influence how many threads are used at max for delivering messages from the mta to dagent. The setting is called lmtp_max_threads and can be found at https://stash.kopano.io/projects/KC/repos/kopanocore/browse/installer/linux/dagent.cfg?at=9f839209662#31-33

                  @fbartels Thanks. It is good idea about DB. I’ve changed

                  lmtp_data_done_timeout = 1200s

                  in postfix config for now. Because I tried to send emails to about 400 test users, it took over 10 minutes to deliver and close connection.

                  Also tuned my MariaDB with

                  innodb_buffer_pool_size = 1G
innodb_log_file_size    = 250M
innodb_log_buffer_size  = 32M
innodb_file_per_table   = 1

                  And add cache tunning in server.cfg

                  cache_cell_size = 1024M
cache_object_size = 10M
cache_indexedobject_size = 50M

                  Watching for result.

                    Are you using the ldap backend of Kopano? If so then the delay could also be related to missing indexes.

                        I cannot find an example log line right now, but in the past OpenLDAP logged when it encountered a query that would benefit from additional indexed attributes.

                            Then it is indeed most likely missing ldap tuning. What is logged between 07:20:08 and 07:29:39 more of the “resolved recipient” messages?

                              I found strange behavior. Message to mailing list sent triple time. It appears in Outbox for a long time. Then in SENT multiply times. From 2 to 7 times. Thus I can make desision - something wrong in webapp.
                              Postfix and dagent deliver this multiple mail.
                              From server log in time when the second email forming appears:

                              2021-05-21T12:16:19.438546: [warning] K-1515: Object not found unknown user "Group1": Group1 not found in LDAP

                              But in GAL this group and its members persist and I can choose it for sending mail.

                              Step by step representation:

                              1. New mail, to Group1 (from GAL)
                              2. Insert to email body text and picture.
                              3. Click Send.
                              4. Email apperas in Outbox for a long time.
                              5. In Sent appears multiple emalis have been sent in the same time.

                                That works just fine here with your steps from below.

                                      @fbartels Not yet. I am trying fix ldap latency. Chache doesn’t help.
                                      i’ve installed one more test kopano with ldap on the same VM. And have’nt such problem. I think the webapp ask ldap for data to make email, didnt get it before timeout. Again make new mail and so on and so on. With fast ldap I cant reproduce it. Working to find out the source of this problem.
                                      Also i’ve there is problem no even with groups, but fit many recicpients >10. Mails arrive twice.

                                        @fbartels So, I did it. With local ldap replica works fine.

                                        Webapp make more than 1 message, when ldap response too slow. I think it is special bug of webapp.
