So uh, do you check that the forward matches the reverse?
Yup, I believe i do. Failure to match forward and reverse puts the score up quite substantially. Theres nothing stopping me from replacing hostname based stuff with IP based stuff - but if someone decides to go and forge their RDNS just to get around my greylisting, well, i'll be flattered...
