    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns.jpberlin.de (glue 91.198.250.3, 2001:67c:2050:1::53:1, zone 91.198.250.3, 2001:67c:2050:103:53:0:1:1); ns3.jpberlin.de (glue 88.198.52.15, zone 88.198.52.15, 2a01:4f8:221:4381::1). Update the glue at your registrar.

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns.jpberlin.de: "9.18.33"; ns2.jpberlin.de: "9.18.33"; ns3.jpberlin.de: "PowerDNS Authoritative Server 4.3.1". Hide or replace the version string.

    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

  • ✗
    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
  • ✗
    TLSA records not DNSSEC-validated
    TLS · These MX hosts publish TLSA records that the resolver could not validate with DNSSEC, so senders ignore them or, if validation fails, may refuse delivery: mx1.heinlein-support.de, mx2.heinlein-support.de, mx3.heinlein-support.de, mx-n.heinlein-support.de.
    #36
  • !
    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: mx1.heinlein-support.de, mx2.heinlein-support.de, mx3.heinlein-support.de, mx-n.heinlein-support.de
    #11
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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-forensics+deutsches-spionagemuseum.de@zzml.de (needs deutsches-spionagemuseum.de._report._dmarc.zzml.de). 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.
    #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:...".
