As far as I know AOL use a variety of spam filtering rules... SPF is just one
of the tools they use to help decide if a message is spam or not.
SPF is designed to detect FORGERY - not spam! (how many times do
we need to repeat that?). If you are using SPF result as part of
a bayesian filter to detect spam (as I am), you'll find that an SPF pass is
actually a weak indicator that the message is spam - due to the enthusiastic
adoption of SPF by spammers with throwaway domains.
What SPF lets me do is whitelist senders without worrying that their
MAIL FROM is forged. All I have to worry about now is zombies taking
over machines authorized to use whitelisted MAIL FROMs.
