    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns1.rrze.uni-erlangen.de (glue 131.188.3.2, 2001:638:a000:1001:53::1, zone 131.188.3.2, 131.188.0.50, 2001:638:a000:1055:53::1, 2001:638:a000:1001:53::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: tuminfo1.informatik.tu-muenchen.de: "9.10.3-P4-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
  • !
    Ends with ?all (neutral)
    SPF · SPF record uses ?all (neutral), which gives no protection against unauthorized senders. Use -all or ~all instead.
    #3
  • !
    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
  • !
    No aggregate reports (rua)
    DMARC · DMARC record has no rua tag, so you receive no aggregate reports about who sends mail as your domain. Add rua=mailto:...
    #19
  • !
    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:...".
