They state "DMARC=Pass" yet they still reject the mail only because DKIM fails (from their point of view of course)? What a nonsense! Why they check DMARC at all if they require *both* SPF *and* DKIM to pass? -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
