It's about mail with one or more Resent-From or Resent-Sender
header fields as far as I'm concerned.

Whatever SSP does (and the more interesting case is a "Bob" who
is completely DKIM-unaware), the mail should not be rejected
by the next receiver(s) no matter what Alice's SSP says.  Bob
is perfectly entitled to resend a mail he got using the header
fields specified in STD 11 or 2822.

Where "reject" is of course the least problematic outcome, but
"annotate as suspicious", the weasel words for "delete", would
be wrong.
