Yes, it is simple DeMorgan’s Theorem where you use
short-circuiting logic.
DMARC says that any FAIL calculated via SPF or DKIM is an
overall DMARC failure. In standard boolean logic is it an OR
condition:
IF SPF FAILS or DKIM FAILS Then Reject.
You have it absolutely backwards.
DMARC says if either (aligned) SPF validates or (aligned) DKIM
validates, it passes.
I don't follow you, so NO
a fail of either is a failure as a whole.
That is how the major EPS of late are applying it - per specs.
