More than one DMARC record was found.

DMARC_MULTIPLE_RECORDS · Severity: Error

• ErrorDMARC_MULTIPLE_RECORDS

  More than one DMARC record was found.

  RFC 9989 says receivers discard all DMARC records at a name that returns more than one, so none of them is applied. Discovery then continues at the parent domains.

  Recommendation: Keep a single DMARC record.
