Problems

  • ✗
    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: dns0.ac-martinique.fr (195.83.254.100): REFUSED, authoritative=false.
    #15
  • ✗
    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: dns0.ac-martinique.fr (195.83.254.100): .
    #19
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: dns0.ac-martinique.fr. pass-ren.ac-limoges.fr, pass3.ac-guadeloupe.fr report NS pass-ren.ac-limoges.fr pass3.ac-guadeloupe.fr.
    #7
  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.
    #27
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (3m), NS (3m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 3m; resolvers may use either.

✓SPF ✗DMARC !DKIM !DNSSEC !MX !TLS iBIMI

Problems

  • ✗
    Policy: none (monitoring only)
    DMARC · DMARC policy is set to 'none', which only monitors but doesn't protect against spoofing. Consider upgrading to 'quarantine' or ideally 'reject'.
    #4
  • !
    No key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
    #7
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: msg-a85.education.gouv.fr, msg-b85.education.gouv.fr
    #11
  • !
    No aggregate reports (rua)
    DMARC · DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...
    #19
  • !
    Not configured
    TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
