Problems

  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns.ecole.ensicaen.fr, nsr.ensicaen.fr. ns.ecole.ensicaen.fr, ns.ensicaen.fr, nse.ensicaen.fr, nsr.ensicaen.fr report NS ns.ecole.ensicaen.fr ns.ensicaen.fr nse.ensicaen.fr nsr.ensicaen.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.

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: default (1024 bits), mail (1024 bits), selector1 (1024 bits), selector2 (1024 bits), mta (1024 bits), s2 (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.
