  • ✗
    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: daisy.ensea.fr (193.51.45.2): SERVFAIL, authoritative=false; daisy.ensea.fr (2001:660:3037:e::1): SERVFAIL, 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: daisy.ensea.fr (193.51.45.2): ; daisy.ensea.fr (2001:660:3037:e::1): .
    #19
  • !
    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: blanche.ensea.fr (glue 193.51.46.142, zone 193.51.46.142, 2001:660:3037:f::1); daisy.ensea.fr (glue 193.51.45.2, zone 193.51.45.2, 2001:660:3037:e::1); tryphon.ensea.fr (glue 193.51.47.205, zone 193.51.47.205, 2001:660:3037:b::1). Update the glue at your registrar.

    Serials differ
    SOA · The nameservers serve different versions of the zone: 2026090704 on tryphon.ensea.fr (193.51.47.205), tryphon.ensea.fr (2001:660:3037:b::1); 202609071 on blanche.ensea.fr (193.51.46.142), blanche.ensea.fr (2001:660:3037:f::1). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.
    #22
  • !
    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.

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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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.
