Does the spam filter learn?

Hi@all,

I have set up the spam filter as described in the documentation. See:

https://documentation.kopano.io/kopanocore_administrator_manual/special_kc_configurations.html#configuring-kopano-spamd-for-automatic-spam-ham-learning

The file /etc/kopano/spamd.cfg looks like this:

run_as_group        = kopano
log_method          =   syslog
sa_group = kopano

The rest are just comments and were removed for posting. I keep receiving advertising mails from the same addresses/senders (with whom I have nothing to do). Although I always mark them as junk in Kopano, the server does not automatically sort them out. As an example I exported a mail as EML and looked at the header.

The mail is processed by amavisd but is not classified as spam. What surprises me is the entry:

autolearn=disabled

Did I forget something during setup or does “sa-learn” still have to be executed via cron?

If I mark this mail as spam in Kopano and look at the syslog at the same time, nothing happens here :frowning:

What did I forget?
