Doing early SPF filtering is against DMARCbis document, as DMARCbis document do require checking both DKIM and SPF, and those who do early filtering of the emails based on the SPF, usually do it before actually seeing the email, thus they do not even know if the emaisl have DKIM headers or not. Anybody doing early stage filtering of mailflows based on the SPF, and not checking DKIM is not following the DMARCbis document, thus they are out of scope of the DMARCbis discussion. You are allowed to do SPF only separately. You are not allowed to do SPF only when you claim to do DMARCbis. I think the current document is clear about that, but perhaps we should make it even more obvious, and explictly say so. -- kivinen@xxxxxx -- last-call mailing list -- last-call@xxxxxxxx To unsubscribe send an email to last-call-leave@xxxxxxxx
