That's probably the reason why much spam has valid spf records. Get yourself
a throwaway domain, so you're getting through the domain check and give that
domain a valid spf record which allows all machines in the world to send 
mail for that domain. Voilà - valid SPF record.

That's why I asked which problem SPF is trying to solve.
