Agreed. In fact, there might just be too many email forwarding
accounts out there to ever have a scheme like SPF work right.
Again I say... this is situationally dependent. Using "MUST NOT" in the
spec is sending the wrong message. The right message is that the domain
admin "MAY USE" -all if they chose based on their individual domain
situation.
