    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (5s), AAAA (8s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 8h; resolvers may use either.

    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.
