There was a little side box in the current Economist that spam was
down from 80+% to 67% and credited it to, among other things
"sophisticated authentication" which I assume means DKIM and SPF.

First is there actual evidence that spam is on the wane? And if so,
does it actually have to due in part with authentication? I'd be
ecstatic to hear that the latter was true, but correlation is not
causation.
