Email security

DScore 50/100 across SPF, DMARC, DKIM, MTA-STS and BIMI.
  • warnDMARC policy is none (monitoring only). Spoofed mail is still delivered.
  • 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).
