Problems

  • ✗
    Nameserver names don't resolve
    Delegation · These nameservers have no A or AAAA record, so they can't be reached (lame delegation): sprodads005.selorp.local, sprodads006.selorp.local.
    #9
  • !
    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: sprodads005.selorp.local, sprodads006.selorp.local. ns1.belnet.be, ns2.belnet.be, ns3.belnet.be, ns3.selor.be report NS ns1.belnet.be ns2.belnet.be ns3.belnet.be ns3.selor.be sprodads005.selorp.local sprodads006.selorp.local.
    #7
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns3.selor.be: "Microsoft DNS 6.1.7601 (1DB15F75)". 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.
    #27
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: NS (3m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1d and in the zone 3m; resolvers may use either.

Problems

  • !
    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
  • !
    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: mailgate.fediap.be
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    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.
