    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: dns01.uni-vechta.de (glue 131.173.82.1, zone 131.173.82.1, 2001:638:726:20::83ad:5201); dns02.uni-vechta.de (glue 131.173.82.2, zone 131.173.82.2, 2001:638:726:20::83ad:5202). 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: dns01.uni-vechta.de: "9.18.39-0ubuntu0.22.04.7-Ubuntu"; dns02.uni-vechta.de: "9.18.39-0ubuntu0.22.04.7-Ubuntu". Hide or replace the version string.

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
  • !
    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: a1181.mx.srv.dfn.de, b1181.mx.srv.dfn.de, c1181.mx.srv.dfn.de
    #11
  • !
    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:...".
