Email security

FScore 49/100 across SPF, DMARC, DKIM, MTA-STS and BIMI.
  • badSPF needs about 11 DNS lookups but the limit is 10. Receivers return a permanent error, so SPF fails. Flatten or remove includes.
  • 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.
  • 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.
  • goodSPF record found.
  • goodSPF ends with ~all: servers you have not listed are marked as suspicious (soft fail).
  • goodDKIM keys found (selector: k1, k2, s1, s2, mail, mandrill).
  • good1 MX record(s) found. Mail is handled by Microsoft 365.
  • goodBIMI record found: supporting inboxes can show your brand logo.
