What would the prefix on a redirect mean? In my opinion: If no (valid) SPF record is found at the target, the redirect mechanism would act like the all mechanism and the prefix would be the default result. Currently, the SPF spec is silent on what should happen in this case. So, if you had "v=spf1 ~redirect:_spf.other-domain.tld", and there wasn't a valid SPF record under _spf, the result would be softfail. -wayne
