SPF or DKIM Invalid

If SPF or DKIM shows invalid, compare DNS output against the records shown in Mailtarget.

Checklist

  1. Confirm the record exists at the expected label.
  2. Confirm there is only one SPF TXT record for the domain.
  3. Confirm the SPF record includes Mailtarget.
  4. Confirm the DKIM selector includes the underscore labels.
  5. Confirm the DKIM value was not truncated.
  6. Wait for DNS propagation if the record was changed recently.
