A plain SPF '-all' to say this domain sends no mail at all works great. Other than that SPF has been somewhat useful for phishes of domains like paypal.com that send all their mail mechanically and don't have human users. (The humans at Paypal use another domain.) SRS was mostly useful as an exercise to confirm that the world is not going to completely change how it works just because the FUSSP du jour can't describe the way it's been sending mail for 30 years.
