Chris,
Maybe I can help you by presenting my simplistic view of SPF.
SPF allows me, as a domain owner, to tell the internet community how they
can determine than an email is actually being sent by my domain. If they
receive an email that fails the SPF check, then it did NOT come from me. If
the recipient email-server-operator decides to then discard that email, that
is their choice.
And I believe that it is the ISP's perogative what policies to implement to
run their business, contrary to what the users want. For example, in my
area, most of the broadband ISP's will NOT give out fixed IP addresses or
allow a user to run their own 'server' at home. (Inbound http, smtp, etc.)
The good thing for me is that there is one ISP that I've found that gives
out fixed IP's and doesn't care what I run on my IP (subject to decency and
abuse provisions, I'd suspect). Similarly, I'm sure that you will be able
to find an ISP (or just an email provider) that won't do SPF checks. As a
user of your ISP, you are subject to the policies that they put into effect.

Hi Rik,
Take a look at mailblocks then - IMHO it's the best implementation
available for anti-spam. SPF isn't designed for spam blocking, so if
you're looking for an anti-spam SPF is not going to solve much.
Unfortunately, for technical reasons, I can't myself use mailblocks,
but everyone I know who uses it swears by it.
There's a few other things that are similar too - I forget the names
of them, though I've been asked to authenticate by them a few times.
And of course - since it's user-to-user, nobody who isn't looking for
spam blocking gets affected (like all the users of an ISP for
example).
Kind Regards,
Chris Drake
