Problems

  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: asia2.akam.net: "48878.29"; asia3.akam.net: "48878.30"; aus1.akam.net: "41824.4"; eur3.akam.net: "48878.33"; eur4.akam.net: "41824.11"; ns1-102.akam.net: "41824.8"; ns1-102.akam.net: "41824.5"; ns1-161.akam.net: "41824.11"; ns1-161.akam.net: "41824.9"; use3.akam.net: "41824.6"; usw1.akam.net: "41824.4". Hide or replace the version string.

    Unusual SOA timers
    SOA · refresh 15m is outside 20m–1d; retry 1h should be shorter than refresh 15m. Current values: refresh 15m, retry 1h, expire 30d, negative TTL 15m.
    #23
  • !
    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.
    #27
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (20s), MX (1m39s), NS (1m39s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1m39s; resolvers may use either.

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
  • !
    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: mxa-00176a04.gslb.pphosted.com, mxb-00176a04.gslb.pphosted.com, mx0a-00176a04.pphosted.com, mx0b-00176a04.pphosted.com
    #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 all MX hosts use DANE
    TLS · These MX hosts publish no TLSA records, so mail to them is not protected by DANE: mxa-00176a04.gslb.pphosted.com, mx0a-00176a04.pphosted.com, mx0b-00176a04.pphosted.com.
