      Incoming spam emails is not sorted into junk folder.
      Why?

      root@kopano:[~]: kopano-server -V

        hi @Blinkiz
        this is my config:
        cat /etc/kopano/dagent.cfg | egrep -v “(^#.*|^$)”
        server_socket = file:///var/run/kopano/server.sock
        log_method = file
        log_file = /var/log/kopano/dagent.log
        log_timestamp = 1
        log_raw_message = no
        log_raw_message_path = /tmp
        log_buffer_size = 4096
        tmp_path = /tmp
        server_bind = 127.0.0.1
        lmtp_port = 2003
        lmtp_max_threads = 20
        pid_file = /var/run/kopano/dagent.pid
        spam_header_name = X-Spam-Status
        spam_header_value = Yes,
        archive_on_delivery = no
        plugin_enabled = yes
        plugin_manager_path = /usr/share/kopano-dagent/python
        plugin_path = /var/lib/kopano/dagent/plugins
        set_rule_headers = yes
        no_double_forward = no
        default_charset = iso-8859-15

        check if spam_header_name = X-Spam-Status works

          @AnotherAndy Am sorry if I was not clear enough. My bad. As you can see in my first post, “X-Spam-Status” does not exist in the incoming email but “X-Spam” does.

            Unless you define some rules, or have some other magical extra component that does it for you, it won’t be moved to Junk.

              @jengelh Hello there. Thanks for replying.
              In the config file /etc/kopano/dagent.cfg it says

              # The following e-mail header will mark the mail as spam, so the mail
# is placed in the Junk Mail folder, and not the Inbox.
# The name is case insensitive.
# set to empty to not use this detection scheme.
spam_header_name = X-Spam

              I read it as the incoming email will be placed in the Junk Mail folder, and not the inbox. Is that not correct?

                Hi @Blinkiz ,
                that’s what I tried to say, use
                “spam_header_name = X-Spam-Status” - without “” in your dagent.cfg
                We had a similar topic here:
                https://forum.kopano.io/topic/125/spam-is-not-sorted-into-junk-folder/4

                  Okay, I changed back to spam_header_name = X-Spam-Status and it still does not work. Again, I do not have a X-Spam-Status header in my incoming emails. I have X-Spam instead.

                    I’m sorry I thought you were also using spamassassin.
                    maybe @jengelh can tell the magic tricks to do

                      I found why it does not work for me. Look at the incoming message I wrote in my first post.

                      root@kopano:[~]: grep -i 'spam' /tmp/raw_messages/LMTP_20181204122623_641be4e6.eml
X-Rspamd-Queue-Id: D428A44FF9
X-Spamd-Result: default: False [11.15 / 15.00];
X-Rspamd-Server: smtp
X-Spam: Yes

                      I then specify to look for X-Spam in my configuration.

                      root@kopano:[~]: cat /etc/kopano/dagent.cfg | egrep -v "(^#.*|^$)"
log_level	=	5
log_raw_message = yes
log_raw_message_path = /tmp/raw_messages
spam_header_name = X-Spam
spam_header_value = Yes

                      Looking at the source code at https://github.com/Kopano-dev/kopano-core/blob/master/spooler/DAgent.cpp i can see that only the first match is returned. In my Message I first have “X-Spamd-Result” which will be the one Kopano is checking against and not “X-Spam” header.

                      This is a bug in the Kopano code.

                          I am suffering from the same bug because still running kopano 8.5.9.0 and an update is being planned. But my question is: can I patch my dagent quickly as shown here?

                          https://stash.kopano.io/projects/KC/repos/kopanocore/commits/2cc0820c6ba1e4698ff0bc4d3e00ff017d737b68

                          what do I need to do to patch my existing kopano-dagent with this bugfix? In my understanding it would me need to modify just the line 2114 in dagent.cpp and somehow compile/update it so I can get a patched kopano-dagent binary. Can anyone show me the correct command and steps therefore? I tried to search for a “dagent.cpp” but no hits on my filesystem.

                          any help appreciated

                            The patch (2cc082) is only in 8.7 and later which, incidentally, made its debut 365 days ago.

                              hehe, nice pic :) does that mean I cannot just change this particular line to get/compile a new kopano-dagent ? are there other/many stuff affected for that patch being able to be effective?

                                @micro You are running a version that was released more than 1.5 years ago. I can’t tell if ‘just patching’ will lead to trouble - I would recommend that you upgrade to the latest version instead and benefit from all the other improvements and fixes.

                                  definitely you’re right. Nevertheless I am curious if this could be a “faster” workaround. It does not mean I will not upgrade, but the upgrade is more time intensive and currently time is very limited along other projects (higher importance). That was just a thought if I could workaround by this.

                                  however, thanks for your reply.

                                    @micro Hello.
                                    To fix his problem without upgrading, change incoming spam header into “X-Spam-Status” or something else that can not match multiple times in your email header. In my case I configure this in rspamd.

                                      that’s exactly what I intented to do when this solution mentioned here not possible. Did you configure this in local.d/worker-proxy.inc ?

                                        I do not remember, sorry. Am running latest version of Kopano now days.
