After staring at RFC7489 and particularly
https:/
cannot obtain a fail in the absence of both an SPF declaration and a
DKIM-signed message. However, I will defer to any superior alien
intelligence which can provide a bible to thump regarding "absence of
pass is fail" as opposed to "lack of both SPF and DKIM precludes
pass/fail evaluation".
