Should I ever clean my Junk folder out?

maybl8

I have a few questions on the junk mail folder.

Is there some documentation on how it works?
Does it ever need to be cleaned out?
Is there a way to know that it is working on a specific junk rule or email?
Is there a guide to show how to adjust settings for it to work the best?
If I use Thunderbird or a different mail client and put mail in the junk folder does it work the same as using sogo to put mail in the junk folder? Some mail clients call it spam but it is the same imap folder as I have seen.
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?
Thanks

Depends on your max. mailbox size

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/

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
