Problems

  • ✗
    Nameserver names don't resolve
    Delegation · These nameservers have no A or AAAA record, so they can't be reached (lame delegation): ns.univ-bordeaux.fr.
    #9
  • ✗
    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: neouvielle.enseirb-matmeca.fr (147.210.18.138): 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: neouvielle.enseirb-matmeca.fr (147.210.18.138): .
    #19
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: edwood.emi.u-bordeaux1.fr; only in the zone: edwood.emi.u-bordeaux.fr. donaser.labri.fr, edwood.emi.u-bordeaux.fr, edwood.emi.u-bordeaux1.fr report NS donaser.labri.fr edwood.emi.u-bordeaux.fr neouvielle.enseirb-matmeca.fr ns.univ-bordeaux.fr.
    #7
  • !
    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: donaser.labri.fr (glue 147.210.8.187, zone 147.210.8.187, 2001:660:6101:404::53). Update the glue at your registrar.
    #8
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: edwood.emi.u-bordeaux.fr: "9.20.23-1~deb13u1-Debian"; edwood.emi.u-bordeaux1.fr: "9.20.23-1~deb13u1-Debian"; neouvielle.enseirb-matmeca.fr: "9.18.30-0ubuntu0.20.04.2-Ubuntu". Hide or replace the version string.
    #17
  • !
    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.

Areas

✓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 DKIM keys published
    DKIM · _domainkey.labri.fr does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #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: mta-in01.u-bordeaux.fr, mta-in02.u-bordeaux.fr, mta-in03.u-bordeaux.fr, mta-in04.u-bordeaux.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.
