To each their own... but most of what I have read over the previous 2-3 weeks is total hearsay (and likely nonsense) in my opinion. Anyone can create emails with headers that pass a homebrewed looking verification engine.
I suppose it's possible that gawneedstobestopped has some connection with this Devon O'Dell (
http://9vx.org/~dho/) and put up a validator that validates DKIM emails properly (I tried a random email on it) **EXCEPT** when it gets one of a set of fake emails created by gntbs in which case it pretends to validate the fake email, but only if the fake email is unaltered. Not very likely, but not absolutely impossible.
