I had bumped the score to 1.0 in 3.2.5 based on my > observations here so looks like I wasn't too far off :-) Maybe, but probably not. The absence of reverse dns is a pretty strong spam indicator, but unfortunately the rule can't distiguish between the absence of rdns and a server that doesn't record it.
