  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns.u-bordeaux.fr. bxnms.u-bordeaux.fr, cnudns.cines.fr, ns.u-bordeaux.fr, ns2.nic.fr report NS bxnms.u-bordeaux.fr cnudns.cines.fr ns.u-bordeaux.fr ns2.nic.fr.

    Unusual SOA timers
    SOA · refresh 36h is outside 20m–1d. Current values: refresh 36h, retry 15m, expire 21d, negative TTL 3h.
    #23
  • !
    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.

  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mta-in01.u-bordeaux.fr, mta-in02.u-bordeaux.fr, mta-in03.u-bordeaux.fr, mta-in04.u-bordeaux.fr

  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (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.
