3things to fix
✗No DMARC record - domain is open to spoofing.▸
Publish a TXT record at _dmarc starting with v=DMARC1; p=none; rua=mailto:you@yourdomain, then tighten it to reject once senders pass.
Read the guide →!No IPv6 (AAAA) record.▸
Add an AAAA record with your server's IPv6 address, or switch on IPv6 at your host or CDN (on Cloudflare it's on by default for proxied records).
!DNSSEC not enabled - enable it to prevent DNS spoofing.▸
Turn on DNSSEC at your DNS host, then publish the DS record at your registrar to complete the chain of trust.
