  • ✗
    Zone transfer allowed
    Nameservers · These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: ns1.ac-strasbourg.fr (2001:660:470f::1): 3212 records; ns2.ac-strasbourg.fr (2001:660:470f::2): 3212 records. Restrict zone transfers to your secondary servers.

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.ac-reims.fr: "9.16.23-RH". Hide or replace the version string.

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'.

  • !
    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.

  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: msg-a85.education.gouv.fr, msg-b85.education.gouv.fr
    #11
  • !
    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.
