Implementing domain validation involves several steps:
Verify Your Domain: This is usually done through the domain registrar or DNS provider. Set Up SPF Records: Specify which servers can send emails on behalf of your domain. Set Up DKIM: Generate a public/private key pair and publish the public key in your DNS records. Set Up DMARC: Create a DMARC record with the appropriate policy (none, quarantine, or reject). Monitor and Adjust: Regularly check your domain’s authentication status and make necessary adjustments.
