Problems

  • !
    No IPv6
    Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.
    #13
  • !
    Unusual SOA timers
    SOA · negative caching TTL (minimum) 1m is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 1d, retry 1h, expire 1000h, negative TTL 1m.
    #23
  • !
    Serial date in the future
    SOA · The serial 2092050401 looks like a date (YYYYMMDDnn) in the future (2092-05-04). It can only grow, so a wrong date can't be undone without a serial wrap-around.

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
  • !
    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: mxa-00a40801.gslb.pphosted.com, mxb-00a40801.gslb.pphosted.com
    #11
  • !
    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: selector1 (1024 bits). Rotate to a 2048-bit key.
    #23
  • !
    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.
