Implementing SPF, DKIM, and DMARC involves adding specific DNS records. Hereâs a brief overview:
1. SPF: - Identify all the IP addresses that send emails on behalf of your domain. - Create an SPF record listing these IP addresses. - Publish the SPF record in your DNS settings.
2. DKIM: - Generate a DKIM key pair. - Configure your email server to sign outgoing emails with the private key. - Publish the public key in your DNS settings as a TXT record.
3. DMARC: - Decide on your DMARC policy (none, quarantine, reject). - Create a DMARC record specifying this policy and the email address where you want to receive reports. - Publish the DMARC record in your DNS settings.
