Hi, I'm looking at the 0.001 scoring for SPF_NONE and scratching my head. This was discussed a bit in early 2015, but maybe it needs revisiting with new perspective.
Surely no one who cares about maintaining their reputation by protecting themselves against spoofing would fail to provide SPF records... So how is this score arrived at? And of Ham, how much of it has a valid SPF? And of Spam, how much of it lacks a valid SPF? Has anyone run some numbers? Thanks, -Philip
