  • ✗
    No DNS over TCP
    Nameservers · DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns1.virtualhosts.de (2a02:e00:fff0:ba::1): dial tcp [2a02:e00:fff0:ba::1]:53: connect: connection refused; ns2.virtualhosts.de (2a02:e00:ffed:90::1): dial tcp [2a02:e00:ffed:90::1]:53: connect: connection refused; ns3.virtualhosts.eu (80.83.124.49): dial tcp 80.83.124.49:53: connect: connection refused; ns3.virtualhosts.eu (2a02:e00:ffec:d8::1): dial tcp [2a02:e00:ffec:d8::1]:53: connect: connection refused.

    No EDNS
    Nameservers · These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: ns1.virtualhosts.de (195.128.160.129), ns1.virtualhosts.de (2a02:e00:fff0:ba::1), ns2.virtualhosts.de (195.68.246.129), ns2.virtualhosts.de (2a02:e00:ffed:90::1), ns3.virtualhosts.eu (80.83.124.49), ns3.virtualhosts.eu (2a02:e00:ffec:d8::1).

    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

  • ✗
    No DMARC record
    DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.
    #5
  • !
    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
  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mail01.virtualhosts.de
    #11
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    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.
