Problems

  • ✗
    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: ccpntc3.in2p3.fr (134.158.69.191): REFUSED, authoritative=false; ccpnvx.in2p3.fr (134.158.69.104): REFUSED, 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: ccpntc3.in2p3.fr (134.158.69.191): ; ccpnvx.in2p3.fr (134.158.69.104): .
    #19
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: ccpntc3.in2p3.fr, ccpnvx.in2p3.fr. dns.univ-lyon1.fr, dns2.univ-lyon1.fr report NS dns.univ-lyon1.fr dns2.univ-lyon1.fr.
    #7
  • !
    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 key under common selectors
    DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.
    #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: insa-smtp.insa-lyon.fr, mx1.relay.renater.fr, mx2.relay.renater.fr
    #11
  • !
    Hosts are CNAMEs
    MX · MX records must point to a host name with A/AAAA records, not to a CNAME: insa-smtp.insa-lyon.fr -> insa-smtp-01.insa-lyon.fr
    #22
  • !
    Report address not authorized
    DMARC · These report addresses are in another domain that has not agreed to receive your reports, so receivers will not send them: mailto:web-applications-metiers@insa-lyon.fr (needs groupe-insa.fr._report._dmarc.insa-lyon.fr). Ask the report provider to publish the record, or check the address.
    #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.
