Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: ns10.silabs.com, ns11.silabs.com, ns12.silabs.com, ns13.silabs.com, ns14.silabs.com, ns15.silabs.com; only in the zone: ns10.dnsmadeeasy.com, ns11.dnsmadeeasy.com, ns12.dnsmadeeasy.com, ns13.dnsmadeeasy.com, ns14.dnsmadeeasy.com, ns15.dnsmadeeasy.com. ns10.dnsmadeeasy.com, ns10.silabs.com, ns11.dnsmadeeasy.com, ns11.silabs.com, ns12.dnsmadeeasy.com, ns12.silabs.com, ns13.dnsmadeeasy.com, ns13.silabs.com, ns14.dnsmadeeasy.com, ns14.silabs.com, ns15.dnsmadeeasy.com, ns15.silabs.com report NS ns10.dnsmadeeasy.com ns11.dnsmadeeasy.com ns12.dnsmadeeasy.com ns13.dnsmadeeasy.com ns14.dnsmadeeasy.com ns15.dnsmadeeasy.com.

SOA · negative caching TTL (minimum) 3m is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 12h, retry 1h, expire 14d, negative TTL 3m.

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.

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: mxa-0024c301.gslb.pphosted.com, mxb-0024c301.gslb.pphosted.com

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: selector1 (1024 bits), s2 (1024 bits). Rotate to a 2048-bit key.

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.
