Thanks I've used the guide from cPFence to upgrade Rspamd and enabled my webui. After that I started configuring autolearning and manually learned in 600 e-mails as spam & ham. Currnetly on a nice 300/300 spam/ham.
That made a insane difference, before tuning the default enhance rspamd configuration did do some spam rejecting but after making the system learn it was a insane big difference.
I know there is a way to auto learn from spam folders, I don't know for sure if this is handy to set up. How would enhance handle this? Besides that, it would be better if this could be integrated within enhance. Something on the enhance side to fix to be fair.
