    Unusual SOA timers
    SOA · refresh 10m is outside 20m–1d; retry 10m should be shorter than refresh 10m. Current values: refresh 10m, retry 10m, expire 1000h, negative TTL 10m.

Problems

  • ✗
    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.
    #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
    #11
  • !
    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:...".
