Email security

CScore 70/100 across SPF, DMARC, DKIM, MTA-STS and BIMI.
  • warnSPF uses 9 of the 10 allowed DNS lookups. Adding another service may break it.
  • 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.
  • warnNo BIMI record (optional: shows your logo next to your emails in supporting inboxes).
  • goodSPF record found.
  • goodSPF ends with -all: servers you have not listed are rejected (hard fail).
  • goodDMARC policy is reject: mail that fails authentication is blocked.
  • goodDMARC aggregate reports are sent to mailto:[email protected].
  • good8 MX record(s) found.
