>>Spammers' primary methodology is using hijacked (infected) PCs as spam
zombies. All you'd know is the id of the hijacked PC, which you already

Except that SPF would stop all of these zombied systems. None of the
mail from them would authenticate. In a world where SPF is followed,
none of the mail is accepted.
