Hello,
Well it depends, DMARC requires both, but a more strict DMARC will
You may be right and I could be wrong but I don't think it works that
way. Note in particular sections 3.1 and 4.2 of rcf7489 [1]. The latter
reads in part "at least one" (not both):
A message satisfies the DMARC checks if at least one of the supported
authentication mechanisms:
1. produces a "pass" result, and
2. produces that result based on an identifier that is in alignment
Anyway - we've drifted a bit off topic from the original dmarc vs
mailing list to 'how does dmarc really work'.
