It would have been preferable that you shared that domain, but it does seem to violate the RFC. The only pecuiar bit I see is that _report._dmarc.emailzustellbarkeit.d e IS set. $ dig _report._dmarc.emailzustellbarkeit.de txt ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 52922 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1 ;; ANSWER SECTION: _report._dmarc.emailzustellbarkeit.de. 7200 IN TXT "v=DMARC1" but the RFC is clear that the wildcard need to be on *._report._dmarc.e mailzustellbarkeit.de, a record on _report._dmarc.emailzustellbarkeit.de wouldn't match (and, if strictly conforming, there should also be a semicolon after "DMARC1") _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
