Publish an MTA-STS DNS record and host a policy file at https://mta-sts.yourdomain.com/.well-known/mta-sts.txt. This tells senders to require TLS when delivering mail to your domain.
Upgrade your DMARC policy from p=quarantine to p=reject for maximum protection. Quarantine flags spoofed messages as spam; reject blocks them entirely.
Publish a TLS-RPT DNS record to receive reports about TLS delivery failures to your domain.
Enable DNSSEC at your DNS provider and add the DS record at your registrar. Many DNS providers (Cloudflare, Route 53, etc.) offer one-click DNSSEC activation.
