I followed this howto: https://www.howtoforge.com/replacing-amavisd-with-rspamd-in-ispconfig/ thank you very much for that. It is working well, except a little on the trigger-happy side. I often see messages that get "soft reject" and then "subject rewrite". I have trained with both HAM and SPAM, including the messages marked wrong, however they are still constantly marked. I have added the senders to the Spamfilter Whitelist, however that doesn't seem to help much either (although I'm still testing). I tried adding the domain as a sender in the Postfix Whitelist, but that does nothing. My global policy is Normal, and individual mailboxes are -none-. I can see the settings I pick in /etc/rspamd/local.d/users however looking at the Rspamd GUI, the messages are being marked before the trigger level I've set. Any help would be greatly appreciated.
