    Unusual SOA timers
    SOA · refresh 2d is outside 20m–1d; negative caching TTL (minimum) 2d is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 2d, retry 1h, expire 20d, negative TTL 2d.

  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (2m), AAAA (2m), MX (2m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 5m; resolvers may use either.

    1024-bit DKIM key

    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.

    Not configured
    TLS · MTA-STS or DANE is used without TLS-RPT, so you get no reports when senders fail to deliver because of TLS problems. Publish _smtp._tls TXT "v=TLSRPTv1; rua=mailto:...".
