Problems

  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns0.sorbonne-universite.fr (134.157.23.111): read udp 46.225.38.91:49707->134.157.23.111:53: i/o timeout.
    #14
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns0.sorbonne-universite.fr, ns1.sorbonne-universite.fr. ganesh.upmc.fr, ns1.sorbonne-universite.fr, shiva.jussieu.fr, soleil.uvsq.fr report NS ganesh.upmc.fr ns0.sorbonne-universite.fr ns1.sorbonne-universite.fr shiva.jussieu.fr soleil.uvsq.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
  • ✗
    No DKIM keys published
    DKIM · _domainkey.jussieu.fr does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #7
  • !
    Ends with ?all (neutral)
    SPF · SPF record uses ?all (neutral), which gives no protection against unauthorized senders. Use -all or ~all instead.
    #3
  • !
    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: shiva.jussieu.fr, soleil.uvsq.fr
    #11
  • !
    Unsupported report address
    DMARC · Receivers only send reports to mailto: addresses: dmarc@listes.sorbonne-universite.fr.
    #29
  • !
    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.
