I think he's confusing SPF and DMARC, or he's just confused. If a domain has no SPF record, the SPF result is None, which is not Pass, so in some contexts (DMARC checks) it acts like fail. This should not surprise anyone. R's, John _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
