Delegation · The nameservers at the parent and in the zone should be the same. Only at the parent: ns-cloud-e1.googledomains.com, ns-cloud-e2.googledomains.com, ns-cloud-e3.googledomains.com, ns-cloud-e4.googledomains.com. ns-1047.awsdns-02.org, ns-1636.awsdns-12.co.uk, ns-276.awsdns-34.com, ns-868.awsdns-44.net report NS ns-1047.awsdns-02.org ns-1636.awsdns-12.co.uk ns-276.awsdns-34.com ns-868.awsdns-44.net. ns-cloud-e1.googledomains.com, ns-cloud-e2.googledomains.com, ns-cloud-e3.googledomains.com, ns-cloud-e4.googledomains.com report NS ns-cloud-e1.googledomains.com ns-cloud-e2.googledomains.com ns-cloud-e3.googledomains.com ns-cloud-e4.googledomains.com.

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.

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (1024 bits), google (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.
