No, I think you're confusing it with DKIM. SPF checks to see whether
the sending machine is an authorized IP address for the domain of the
envelope FROM address --- which'd be the list itself. For example,
the whine I'm getting about this message is

Received-SPF: none (sss.pgh.pa.us: domain of postgresql.org does not provide an SPF record) client-ip=217.196.149.56; envelope-from=sss(dot)pgh(dot)pa(dot)us(at)postgresql(dot)org; helo=malur.postgresql.org;

The original sender having been stark(at)mit(dot)edu doesn't enter into it.
