Where to find the GUI control area mentioned by Taleman in this post? He mentions that he has the ability to train the filters as ham/spam and can review logs of it's actions. Currently, all I see that is available to me in my Control Panel are 4 settings. Also, which headers are being added by this Rspamd? is it the nice X-Spam headers (they have a nice lot of info in them) but if X-Spam headers are from Amavis then I'm worried that we will have even less ways to understand how Rspamd is working in the future after Amavis is removed?
