DKIM finding
DKIM body hash mismatch
The body hash in the DKIM signature does not match the actual message body. Something changed the content after it was signed.
Finding code
dkim_body_hash_mismatch
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.
Something changed the message body after it was signed. Common causes: a mailing list that appends a footer, an antivirus gateway, or a forwarding rule that modifies content. Sign after the last transformation, not before.
