Instead, I would recommend that receivers whitelist their forwarders

they would use in MAIL FROM if they rewrite the MAIL FROM like they should.
Ummm. That is a contradiction. :-) What I mean is, it would be nice if
the forwarders did SRS, but the SPF based whitelist is just as good
when keyed to the recipient.
