Problems

  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.ntdns.de: "PowerDNS Authoritative Server 4.1.1"; ns2.ntdns.de: "PowerDNS Authoritative Server 4.1.1"; ns3.ntdns.de: "PowerDNS Authoritative Server 4.1.1". 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.

iSPF ✗DMARC !DKIM !DNSSEC !MX !TLS ✗BIMI

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
  • ✗
    DMARC not strict enough for BIMI
    BIMI · Mail clients will not show the logo. BIMI requires DMARC p=quarantine or p=reject (now p=none), a subdomain policy other than sp=none.
    #39
  • !
    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: mx01.hornetsecurity.com, mx02.hornetsecurity.com, mx03.hornetsecurity.com, mx04.hornetsecurity.com
    #11
  • !
    Policy disabled (mode: none)
    TLS · The MTA-STS policy is switched off with mode: none.
    #33
  • !
    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.
