Currently Rspamd is the default email mamager used by your Entity Agent in your Private Cyberspace (assuming you are an average home user).
Your application integrator should have Rspamd set up with usable defaults, so you do NOT need to touch it unless you are not satisfy with the result, you can then take charge and tune rspamd as much as you like yourself.
