Email security

DScore 54/100 across SPF, DMARC, DKIM, MTA-STS and BIMI.
  • warnDMARC policy is none (monitoring only). Spoofed mail is still delivered.
  • warnDMARC has no rua= address, so you receive no reports about mail sent as your domain.
  • warnDKIM key found (selector: default) but it is only 1024 bits; 2048 is recommended.
  • 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 marked as suspicious (soft fail).
  • good3 MX record(s) found.
