Most of the technology issues aren't appropriate for this list, either, so
I suspect you care less about the propriety than your particular interest.

As an end-user, nothing.  http://spf.pobox.com/users.html.  Same site for
a general FAQ which addresses implementation (it's done via DNS records).
The Slashdot article had a link to the Microsoft implementation; the
complaint about it is that they are releasing a free license to implement,
which can be revoked at any time.
