Without giving up SPF's mailing list FP immunity, it gains the same
forwarding FP immunity DKIM/ADSP has.


It would work smoother than a mere "reject mail only if DKIM/ADSP and SPF
both say Fail" policy, because the mailserver would know in advance
whether it is worthwhile to let an incoming SPF-fail transaction proceed
to DATA.
