So far both spammers and those who understand SPF have adopted it. I have, AOL
has, even has adopted it.. (dig txt

Lots of nonspammers have SPF records in use.

 Those who don't understand SPF claim it's useless because they expect it to be
an anti-spam technology and realize that spammers can easily create their own
SPF records... But that whole argument is invalid as SPF isn't an anti-spam
technology per-se.

Passing SPF isn't a good indicator of nonspam. It's forgable, and we all know
it. It's failing SPF that's useful, as it will eventualy force spammers and
worms to stop forging their domains, making them easier to track.
