Problems

  • ✗
    Nameserver names don't resolve
    Delegation · These nameservers have no A or AAAA record, so they can't be reached (lame delegation): lagaffe.univ-angers.fr.
    #9
  • ✗
    Zone transfer allowed
    Nameservers · These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: atlas.uco.fr (193.49.1.65): 1758 records; ns2.uco.fr (192.93.219.2): 1758 records. Restrict zone transfers to your secondary servers.
    #18
  • !
    Expires in 15 days
    Registration · The registration expires on 2026-11-06. Make sure it is renewed.
    #3
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: lagaffe.univ-angers.fr. atlas.uco.fr, ns2.uco.fr, resone.univ-rennes1.fr report NS atlas.uco.fr ns2.uco.fr resone.univ-rennes1.fr.
    #7
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: atlas.uco.fr: "9.16.23-RH"; ns2.uco.fr: "9.8.2rc1-RedHat-9.8.2-0.68.rc1.el6_10.8". 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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits), selector1 (1024 bits), s2 (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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:dmarc@eudonet.com (needs uco.fr._report._dmarc.eudonet.com). 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.
