That's not the right direction.

Only SWK-SPF does this.
Wrong direction -- extend things so that the whitelist can hold
non-email-address tokens, like hostnames from rDNS or HELO. This is
dangerous because whitelist entries to support a given forward may have no
obvious connection to the forwarding, tempting lusers to "garbage collect"
them out of their lists.
OK, I understand you mean "right direction" as "right thing to do". I read it
as something to do with the direction of mail flow. English is a terrible
language when we need clear, unambiguous communication! :>(
I'm still not understanding something. Maybe it's what problem are we trying
to solve. I'm thinking about Problem S, which I would state even more
succinctly as "Forwarder not recognized by downstream Agent". The solution I
suggested (MDA allowing the Recipient to whitelist the Forwarder's domain)
works for me as a Recipient, but may not be a good solution in all situations.

My MDA is yahoo.com. They allow me to whitelist individual Senders (e.g.
tom(_at_)aol(_dot_)com), but not all mail coming from box67.com (my Forwarder).
I have accomplished the desired result by setting up a private account at
yahoo.com, and turning OFF all spam filtering on that account. As long as I
can keep the address of my private account secret, it's as good as a secure
channel from my Forwarder to my MDA.
What situation are you thinking of?
