Put another way, if I publish (correct) SPF records for my domain, and
then send a message to A, who forwards to B, who then applies SPF
checks and bounces the mail, it should be clear from the spec that
it's B that's at fault, and not me. Publishing SPF records mustn't
carry with it a responsibility not to send mail to mail forwarding
accounts, since that's clearly unworkable (and will act as a
disincentive to publish the records).
Also, we should be careful to document that SPF breaks the resent
functionality documented in the SMTP RFC (2822) section 3.6.6.
