      @bbc said in dagent problem:

      How can I check it?

      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.
