  • ✗
    Nameservers not responding
    Nameservers · These addresses did not answer, so resolvers waste time on timeouts: ns1.univ-reunion.fr (195.220.150.17): read udp 46.225.38.91:40403->195.220.150.17:53: i/o timeout; ns2.univ-reunion.fr (194.199.73.30): read udp 46.225.38.91:52418->194.199.73.30:53: i/o timeout.

    Lame delegation
    Nameservers · These nameservers don't answer authoritatively for the zone, so resolvers ignore them: ns1.renater.fr (193.49.159.2): SERVFAIL, authoritative=false; ns1.renater.fr (2001:660:3001:4002::2): SERVFAIL, authoritative=false; ns2.renater.fr (193.49.159.9): SERVFAIL, authoritative=false; ns2.renater.fr (2001:660:3001:4002::9): SERVFAIL, authoritative=false.

  • ✗
    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: ns1.renater.fr (193.49.159.2): ; ns1.renater.fr (2001:660:3001:4002::2): ; ns2.renater.fr (193.49.159.9): ; ns2.renater.fr (2001:660:3001:4002::9): .

    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns1.renater.fr, ns2.renater.fr. soleil.uvsq.fr report NS ns1.renater.fr ns1.univ-reunion.fr ns2.renater.fr ns2.univ-reunion.fr soleil.uvsq.fr.

  • !
    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

  • ✗
    DMARC not strict enough for BIMI
    BIMI · Mail clients will not show the logo. BIMI requires DMARC pct=100.
    #39
  • !
    Policy: quarantine
    DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.
    #4
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    More than 5 MX records
    MX · Found 7 MX records, which is more than the recommended maximum of 5. Too many MX records may indicate a misconfiguration.
    #13
  • !
    Applies to 25% of mail
    DMARC · DMARC policy only applies to 25% of failing mail (pct=25). Raise pct to 100 once you are confident in your setup.
    #18
  • !
    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.
    #32
  • !
    No certificate (a=)
    BIMI · The logo is published without a Verified Mark Certificate. Gmail and Apple Mail only show BIMI logos with a VMC or CMC; Yahoo shows it without one.
