Contrary to the promotions, SPF will not stop spam.
Who is promoting SPF as an anti-spam solution? I'd really like to
know.
Let's take a look at http://spf.pobox.org. Hey, look what it says:
SPF is ushering in a new set of anti-spam systems, where email is
spam unless proven otherwise.
If history is any guide, some SPF fan will write back in a
huff and say "That doesn't say SPF is an anti-spam solution!
It just says that SPF is holding a flashlight and will lead
the actual anti-spam solutions to their seats!"
This kind of disingenuous doubletalk has characterized SPF
advocacy since its beginning, and is one of the many reasons
that the mainstream e-mail tech community holds SPF in
disdain. That along with its egregious design mistakes and
its irreparably enormous error rate, of course.
SPF can help whitelist mail from fixed source senders you
already know. That's what AOL uses it for, and it's an
adequate if overly complex means to that end. If the SPF
crowd promoted it for that purpose, I don't think anyone
would have a problem with it. But they don't and the smoke
long ago became unbreathable.
