esackbauer Yes, as both will use dovecot in the background. And dovecot noticing mails in and out of the junk folder will trigger junk learning.
Be carefully whit this, I just come across Outlook that in case of internationalization just make own folder (real folder) and do not use /.Junk/. So far I do not know hot to solve this :-( Thunderbird works whit /.Junk/ as intended even in case of internationalization.
Also look for this docs it could be handy https://docs.mailcow.email/manual-guides/Dovecot/u_e-dovecot-expunge/
maybl8 I would like to trace a message as it enters the mail server and see how it is working. Can this be done with mailcow?
So far you can use Logs in UI, Rspamd UI or print log by docker logs command. I’m sending logs from docker to external service to future processing by this https://docs.mailcow.email/post_installation/firststeps-logging/#logging-drivers
