this point is simply wrong a spam-farm CAN NOT set a SPF that whatever ip is allowed to send mails with my envelope - simply because they are not the dns-admin of my zones SPF is NOT a spam-protection it is designed to prevent forged sender-addresses which in the worst case results in multiple auto-replies between completly univolved persons which may over-react and start blacklisting servers which are not the root-cause the real problem is that not EVERY domain has SPF records and that is why it doe snot help as much as it could, you are part of this problem because ANYBODY can send me spam with yur sender-address and only blacklists and bayesian filters prevents my server to send you auto-replies for such messages if i am at vacation
