Actually, any kind of guess is contrary to SPF, since the recipient
provides the record, not the sender. Doing zone cuts, whether to
find an SPF record published by the sender for a parent domain, or
a local record provided by the recipient, are not SPF because the
recipient is guessing the sender's intent. We're just talking
about different variations of a best guess that might handle
forwards in the absence of SRS, and in the absence of SPF records
for the forwarder's HELO FQDN's.
Just to reiterate, the "pretend" MAIL FROM is *not* a HELO FQDN. It
is the actual forwarder domain, the original "rcpt to".
