DKIM finding

DKIM alignment failure

The DKIM signing domain does not align with the From header domain, so DMARC cannot pass via DKIM.

Finding code

dkim_alignment_fail

This finding appears in the findings array of the spam checker and the POST /v1/sender API response when the condition above is detected.

How to fix it

The fix.

The DKIM d= domain does not match the From header domain. For DMARC to pass via DKIM, the signing domain must align with the visible sender. Use your own domain to sign, not the ESP default.
