It has been reported that AOL is already using SPF to give reduced
filtering to SPF-using domains. Is this a good idea?
On its own - no.
Fortunately, it's not what they're doing - they're using SPF for
exactly what it was intended - as part of their reputation system.
They use SPF to confirm that a mail purporting to come from an
organisation on their whitelist is not forged.
Domain on whitelist + SPF Pass = less filtering.
This is exactly what I said. And this is a bad idea for the reasons I
posited.
