D mark SPF protects the sender and like the letterhead and not the envelope. If an email does not like is not accepted by the receive and it's bounced, then the bounce is sent to the address that is on the envelope. So if you don't have both SPF checks and the signature check is failing, then teamwork tells the males are what to do with this message.
