Kopano spamd error - PermissionError: [Errno 1] Operation not permitted


  • Kopano

    @cblaha this is not what the documentation tells you. Additionally I am not sure if spamd uses sudo at all.



  • @fbartels: So, i don’t understand the documentation. Must i add the user to the group amavis?


  • Kopano

    kopano-spamd by default runs in the user context of the user kopano (as defined by run_as_user and run_as_group). To succesfully run sa-learn make sure that the provided user is both part of the amavis group (so spamassasin can process the item), as well as local_admin_user within Kopano (so kopano-spamd has access to the users mailboxes).

    Yes, you could add the Kopano user to the amavis group.



  • I am so desperate. This is my /etc/group

    amavis:x:116:clamav,kopano
    kopano:x:996:kapi,konnect,amavis,spamassassin
    spamassassin:x:1007:kopano
    spamd:x:5555:spamassassin,kopano

    The Logfile always shows:

    Whats wrong with my configuration?


  • Kopano

    Using the default configuration? Would need to check on a test system next week.

    For some dedicated attention I would recommend to open a support case.


  • Kopano

    It certainly is a bit strange. I did some test as wekk and I get the same error message:

    2019-01-02 15:52:15,041 - spamd - INFO - Learning message as SPAM, entryid: 00000000D5713A05C54F4CBB9899E84DD9B593FE0100000005000000548FAD18C4534CA78B2374C46D55FD2700000000

    what makes it even stranger, what the script does when giving the error is a chown, and doing this manually works: sudo -H -u kopano chown kopano:amavis /var/lib/kopano/spamd/spam/E6F09EA690A54940988C8C8467345422.eml

    Will need to check with a python developer tomorrow.

    PS: nevertheless I updated the manual to make the steps more clear and also added a hint to the repo where you got that sudoers stuff from that the content of the repo are outdated. https://documentation.kopano.io/kopanocore_administrator_manual/special_kc_configurations.html#configuring-kopano-spamd-for-automatic-spam-ham-learning


  • Kopano

    Diving into this caused quite some head scratching. The issue is caused by failing over to the bundled daemon module in python-kopano, which was still required in the python2 world, but not anymore in python3. The issue should go away when you install the python3-module manually. We will add this as an official dependency soon.

    https://packages.debian.org/stretch/python3-daemon



  • I have tried it now also in the newest Version (kopano-spamd_8.7.80.424.3b35b58f3-0+49.1_amd64.deb) but also there is the problem not fixed:

  • @BMWfan

    Did you install python3-daemon manually as suggested by @fbartels ?

    Assuming you’re running Debian: apt-get install python3-daemon



  • @fbartels: I’ve installed python3-daemon via apt-get but I get the error already.



  • @ashceryth yes, but i doesn’t work.



  • @fbartels have you changed more then only installing the python-deamon?



  • try both
    apt install python-daemon python3-daemon

    and/or
    apt install python-daemonize python3-daemonize

    And what are the rights on : /var/lib/kopano/spamd/spam/
    i havent looked at my system, but the rights are probley 755
    you can try
    chmod -R 1770 /var/lib/kopano/spamd

    adduser spamassassin kopano
    adduser amavis kopano

    restart spamassassin and amavis



  • I’ve now installed

    python-daemon, python3-daemon,python-daemonize, python3-daemonize

    but i got always the same error message.

    I always changed the permission on /var/lib/kopano/spamd and add the user to the group kopano.



  • @thctlo i’ve already done and now again without any progress depending on the failure.



  • i have the same problem on centos 7.

  • Kopano

    which version of python3-daemon are you using? so we can try to reproduce the problem here…



  • @mark-dufour

    Hi mark i am using python3.6.

    iam starting the service like this

    0_1547131538467_671c1cb3-539f-4645-aa24-3df9199628b9-image.png



  • @mark-dufour here is the needed output from a Debian 9 Server:

    $ pip3.5 list
    Package           Version
    ----------------- -------
    python-daemon     2.1.1
