Giving 5.5 points to a host without reverse DNS makes no sense. Of course it's your rules, and you slightly advocate being cautious, but still someone could think that Botnet is FP safe by default. You are much better off doing all the things that Botnet does in your MTA. Block dynamic HELOs, greylist hosts without DNS/with dynamic DNS.
