No, that's not what SPF gives you. SPF _only_ allows you to know about
the last hop -- the mailhost which actually gave you the email. You know
nothing about the original sender unless the mail happened to be
delivered directly.

Your best best is to contact the site(s) which perform SRS on mail sent
to you, and ask them not to.
