Public Junk folder and RSPAMD training?

Support

NethServer Version: 8
Module: mail

I am migrating my current mail server to NethServer 8 and have configured my mail instance to allow unsolicited emails and store them in the default Junk folder.

I want this to be a catch all account.

I am wondering if items in the Public Junk folder are also auto learned as spam when received/put there (and perhaps.possibly as ham when removed from it when I forgot to setup an alias).

I have tried to find information on this in the documentation but have not found details on the public Junk folder.

migrating from where ?

from what I tested, only when you drop an email to the junk folder of the user is training rspamd, if you check the log, the public folder is useless, what do you think @davidep

From other open source Small Business Servers (ClearOS and SME Server/Koozali). I seem to remember you being active in the SME Server (currently Koozali) community in the past if not mistaken.

True, we are a lot from SME Server or from ClearOS

The spam learning actions are configured here and, as already mentioned by Steph, they are triggered only by the user’s Junk folder:

https://github.com/NethServer/ns8-mail/blob/0043f042fb50fd2b37ef7af968d73feca166ba93/dovecot/usr/local/lib/templates/local.conf#L156-L164

As an idea, you could define similar actions for Public/Junk as well. To do so, try extending the plugins {} section as explained in the documentation:

https://github.com/NethServer/ns8-mail/blob/main/README.md#dovecot-custom-configuration

For reference, see the official Dovecot 2.3 documentation on imapsieve mailbox configuration:

https://doc.dovecot.org/2.3/settings/pigeonhole-ext/imapsieve/#pigeonhole_setting-imapsieve_mailboxXXX_name

Note that we’ll soon upgrade to Dovecot 2.4, and the configuration format is expected to change.
