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 · expire 1h is shorter than 7d; secondaries stop answering too soon when the primary is down; expire 1h must be longer than refresh + retry; negative caching TTL (minimum) 7d is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 3h, retry 1h, expire 1h, negative TTL 7d.
    #23
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: MX (1m). Low TTLs are useful just before a planned change.

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.

    Hosts without IPv6
    MX · The following MX hosts could not be resolved to IPv6 addresses: eu-smtp-inbound-1.mimecast.com, eu-smtp-inbound-2.mimecast.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.
