Yeah, but a fail doesn't magically turn into a pass if you turn -all into ~all. I don't think either is a universal use case, but I see good reasons for both ways and it depends on what type of company and mail sender you are. For me, I think -all makes a lot of sense for marketing senders and folks really worried about phishing/spoofing. And I see lots of -all mail get forwarded just fine, thanks to, for example, the fine folks at Google who write the return path when forwarding. :) Old school forwarding is still a pain even if you pull SPF out of the equation, no?
