Problems

  • !
    Nameservers in one network
    Delegation · all IPv4 addresses are in 134.58.126.0/24; all IPv6 addresses are in 2a02:2c40::/48. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).
    #10
  • !
    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

  • ✗
    No SPF record
    SPF · No SPF record was found for this domain. SPF is important for preventing email spoofing. Add an SPF record to specify which servers are authorized to send email for your domain.
    #6
  • ✗
    No DKIM keys published
    DKIM · _domainkey.kuleuven.ac.be does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.
    #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: kromsin.cc.kuleuven.ac.be, limbak.cc.kuleuven.ac.be, cavin01.kuleuven.be, cavin02.kuleuven.be, cavin03.kuleuven.be
    #11
  • !
    More than 5 MX records
    MX · Found 6 MX records, which is more than the recommended maximum of 5. Too many MX records may indicate a misconfiguration.
    #13
  • !
    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@kuleuven.be (needs kuleuven.ac.be._report._dmarc.kuleuven.be). 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.
