    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-191.akam.net: "41824.5"; a1-191.akam.net: "41824.10"; a12-64.akam.net: "48878.31"; a12-64.akam.net: "48878.29"; a18-65.akam.net: "48878.32"; a18-65.akam.net: "48878.33"; a20-66.akam.net: "48878.30"; a20-66.akam.net: "48878.33"; a3-67.akam.net: "41824.10"; a3-67.akam.net: "41824.4"; a7-64.akam.net: "41824.9"; a7-64.akam.net: "41824.4".

Problems

  • !
    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
  • !
    Signatures expire in 69h0m0s
    DNSSEC · DNSKEY signatures expire at 2026-10-25T12:29:22Z (in 69h0m0s). Check that re-signing works.
    #21
  • !
    Hosts are CNAMEs
    MX · MX records must point to a host name with A/AAAA records, not to a CNAME: mx1relay.faceworks.nl -> mx.spamexperts.com, mx2relay.faceworks.nl -> fallbackmx.spamexperts.eu, mx3relay.faceworks.nl -> lastmx.spamexperts.net
    #22
  • !
    Addresses without reverse DNS
    MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 2001:550:2:61::2fc:100 (mx3relay.faceworks.nl). Ask your hosting provider to set one.
    #30
  • !
    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.
