Another way of saying that SPF "-all" is a gross oversimplication of sender 
identity.  It attempts to say that senders are IP addresses of mail relays, 
when in fact senders are human beings.  The closer you can get to signing 
actions the humans do to send, the closer you are not making a false assumption.
