The Key to Stopping Unwanted Email: Sender ID Can't Do It
Recent proposals to develop sender authentication standards such as
Sender ID are both impractical and inherently flawed. Spammers and
hackers won't wait--and may actually be able to exploit the
registration of IP addresses with Sender ID to improve their junk
mail delivery. Download the latest Postini white paper that explains
why enterprises do not need to rely on the prospects of Sender ID.

I couldn't read it because I'm blocking doubleclick....
Here are the mentions of SPF:
John Levine, chairman of the Anti-Spam Research Group (ASRG) notes that
"Despite occasional comments to the contrary, no one has actually tried out
SPF or Sender ID or anything else. And since the e-mail system is so large,
you've really got to try it out to see where it breaks and how hard it is to
fix the breaks and how much damage it causes." (1)

The whitepaper appears to me to be just an advert by Postini for their
products. In the end, you end up at:
