SOA · The nameservers serve different versions of the zone: 2009014669 on ns10.dnsmadeeasy.com (208.94.148.4), ns10.dnsmadeeasy.com (2600:1800:10::1), ns11.dnsmadeeasy.com (208.80.124.4), ns11.dnsmadeeasy.com (2600:1801:11::1); 2018122801 on ns-383.awsdns-47.com (205.251.193.127), ns-383.awsdns-47.com (2600:9000:5301:7f00::1), ns-750.awsdns-29.net (205.251.194.238), ns-750.awsdns-29.net (2600:9000:5302:ee00::1). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

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 (1m), MX (1m). Low TTLs are useful just before a planned change.

DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

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

MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

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.
