Market forces are intended to penalize companies that do stupid things and if we interfere in those market forces, it will only encourage more stupid things. Or you could look at it this way: RCVD_ILLEGAL_IP was a really good spam indicator until Microsoft messed up, so by using those IPs Microsoft is helping spammers by forcing spam-fighters to reduce or abandon a pretty good rule. Should that sort of behavior be rewarded?I presume detecting forged Received headers was the point of this rule all along, so if we all toss this rule out the window (or adjust to exclude this edge case), aren't we potentially encouraging spammers to "hide" their true networks in the same way?
frankly i don't care for *internal hops* but for the IP delivering mail which can not be forged
It occurs to me that if MS are the only people who are doing this, a meta-rule could counteract the score in that specific case. If it gets used much beyond that by legitimate actors though, that's a whole other story
looks like you are new on this list otherwise you would know that not so long ago Yahoo did hit the same rule
my "problem" with that rule is that it hits practically no spam but only ham and so it goes in the wrong direction entirely and the same happened in the *ther direction* with "RP_MATCHES_RCVD" which is now "T_RP_MATCHES_RCVD" and so no longer has impact for people not aware
both are rules doing nothing good
