Problems

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.kgrz-ks.de: "PowerDNS Authoritative Server 4.8.0"; ns2.ekom21.de: "PowerDNS Authoritative Server 4.8.0"; ns3.ekom21.de: "PowerDNS Authoritative Server 4.8.0"; ns4.ekom21.de: "PowerDNS Authoritative Server 4.8.0"; pdns.kiv-host.de: "PowerDNS Authoritative Server 4.8.0". Hide or replace the version string.

  • !
    NSEC3 with extra iterations or salt
    DNSSEC · NSEC3 uses 10 iterations and a 5-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.

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
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mx3skas.kgrz-ks.de, mx4skas.kgrz-ks.de, mx5skas.kgrz-ks.de
    #11
  • !
    Subdomains unprotected (sp=none)
    DMARC · DMARC subdomain policy is sp=none, so spoofed mail from subdomains is not blocked. Consider sp=quarantine or sp=reject.
    #20
  • !
    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.
    #32
  • !
    Not configured
    TLS · MTA-STS or DANE is used without TLS-RPT, so you get no reports when senders fail to deliver because of TLS problems. Publish _smtp._tls TXT "v=TLSRPTv1; rua=mailto:...".
