I have to admit I'd never paid much attention to the RCVD_IN_DNSWL_* scores
on spam before.
Looking at spam for last month, I don't have a single RCVD_IN_DNSWL_MED.
But I do have 12 pretty blatent spams that hit RCVD_IN_DNSWL_HI.
It makes me wonder just how useful a rule it is.
Especially when it includes sendgrid as part of the "HI" reputation senders.
