SOA · retry 1d should be shorter than refresh 1d; expire 1d is shorter than 7d; secondaries stop answering too soon when the primary is down; expire 1d must be longer than refresh + retry; negative caching TTL (minimum) 1m is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 1d, retry 1d, expire 1d, negative TTL 1m.

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.

Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (4s), AAAA (8s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1d; resolvers may use either.

DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.

DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

MX · The following MX hosts could not be resolved to IPv6 addresses: us-smtp-inbound-1.mimecast.com, us-smtp-inbound-2.mimecast.com

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.
