John Levine has put his finger on the root of the SPF problems, and
co-incidentally the reason for my own non-participation in spf work now.
SPF is not and never will be an anti-spam protocol, and must never be
promoted as such.
spf.pobox.com is the worst possible vehicle for promoting spf.
The council needs to take spf.pobox,com down - better it was a dead link
than to be putting forward such views, and using spf so badly itself.
Meantime we must promote SPF as a means of confirming MAILFROM against
the spf record.. More will come in time, but we have wasted sooooo much
time already that I have given up until the council clarifies this.
Personally, I think 95% of the discuss list is irrelevant to what Wayne
is trying to do - document an existing usage. It is useful in the
context of spf3 but that is some way off.
Slainte,

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.
