Er, the whole point was they they can't _tell_ which mail is from
forwarders, 'configured' or otherwise. Thus the only safe answer is not
to reject for SPF failure at all.
Uh, I thought your claim was that, in your opinion, it wasn't
"feasible" for receivers to tell, not that they "can't" tell.
Anyway, I disagree that it isn't feasible, but that's just rehashing
an old argument.
