Hi tpeel, The Automatic Configuration options that you are seeing are different profiles for the Anti-Spam. In the majority of cases, we always recommend the default setting, Automatic. To answer your question, FP stands for "False positive." For example "Focused on minimizing FP" will introduce less severe parameters so that the possibility that valid email is considered as spam is low, but at the same time it is probably that some spam is not being classified correctly. On the other hand, "Focused on maximizing the success rate" will introduce more restrictive parameters where more spam will be captured (with the risk that more valid emails could be considered as a spam, FP).
