Response to: SPF is broken

I cannot figure out what's a "wild 'net" host. Therefore it is absolutely not clear to me why it should be exempt from SPF.


SMTP provided a Return-Path for bounces assuming users to be polite enough to set it to the real address of the sender. Since spammers are not polite, SPF corrects just that. What's broken?
