Here some results of some 'unconventional' rbl that worked great in my system, I tested spam/ham in the most true mode possible, adding the score that each rule give to consider a spam in count For example, if a rule that have a score of 5 i count spam emails that have this rule and a score of 4 (default) + 5 (rule score) = 9
