I know a few (relatively) large "free email" providers who have done just that. The problem of spam has grown painful enough in size. So who knows, maybe we are on "threshold of spam-inflicted pain" of sorts.
Having said that, as previous poster wrote, no rdns might be very useful for merely increasing spam score in SA.
So, thoughts how to do this in Exim?
Passing the acl_m variable to SA is easy, but I still have little idea how to organize Exim detecting no revdns part.
