FScore 30/100 across SPF, DMARC, DKIM, MTA-STS and BIMI.
  • badNo DMARC record. Receivers have no instructions for mail that fails SPF and DKIM, and you get no reports about who sends as your domain.
  • warnNo DKIM key found at common selectors (google, selector1, selector2, default, k1, k2, s1, s2, ...). DKIM may still use a custom selector we cannot guess.
  • warnNo MTA-STS: mail sent to you can be downgraded to an unencrypted connection.
  • warnNo TLS-RPT record, so you won't hear about failed encrypted deliveries.
