Yeah.  Too bad that among SPF's many flaws is that it completely
confuses the HELO domain and the MAIL FROM domain (and on a bad day,
the domains in From:, Sender:, Resent-From:, and Resent-Sender:.)

SPF 2.0 was supposed to let you specify which contexts each record is
supposed to apply to, but I agree that it'll never get any traction.
