How did you calculate that "40% of my legitimate email"? If you get 60 emails from 60 different hosts that have revDNS and you get 40 mails from two hosts without revDNS then also "40% of your legitimate email" is coming from servers without revDNS, but in fact the precentage of servers without revDNS would be around 3.2%. Quite a difference.
Which would mean that if Suresh insisted on revDNS, he'd end up blocking only 2 hosts, but 40% of his legitimate mail would be dropped on the floor. I'd *hope* that knowingly dropping 40% of the *legitimate* mail on the floor would be considered a CLM. But these days some providers seem to think "all of Europe" is a reasonable filter.....
