DMARC result for the domain in the received message's From header.

  • pass: SPF or DKIM passed and aligned with that domain.
  • fail: DMARC was evaluated and did not pass.
  • unknown: no trustworthy verdict is available.

This follows dmarc_pass and does not verify a particular person. The receiving provider currently supplies no DMARC result, so received messages report unknown.

Possible values: pass, fail, unknown, null

required

Whether the receiving provider reports that SPF authorized the envelope sender for the sending server. A soft failure is false. Missing, neutral and inconclusive results are null.

dkim_pass
nullable boolean
required

Whether the receiving provider verified a DKIM signature. A passing signature makes this true even when another signature fails. Missing signatures and inconclusive verification results are null.

dmarc_pass
nullable boolean
required

Whether SPF or DKIM passed and aligned with the domain in the message's From header. The receiving provider currently supplies no DMARC result, so this is null.
