I realize this is not your point, but as this is a relatively technical
mailing list a distinction is important:  The "From:" field is not the
envelope sender, and we have no indication here that the envelope sender
was altered to match the "From:".

Correctly implemented SPF doesn't care what the From: is.  Assuming SPF
was implemented correctly (which is probably a leap ;-), that basically
means that the envelope sender _was_ generated in sync with the user
supplied email address, and we can't be sure what the From: was, tho,
the bounce might make that clearer.
