How to fill out DNS-based email sender authentication:

1. Choose the appropriate authentication method: DNS-based email sender authentication provides different methods such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance). Identify which method is required or recommended for your email sending platform.
2. Set up SPF record: SPF allows the email recipient's server to verify that the email originated from an authorized server. To set up SPF, add a TXT record to your domain's DNS settings, specifying the list of authorized servers that are allowed to send email on your behalf.
3. Configure DKIM signature: DKIM adds a digital signature to your outgoing emails, ensuring that they are not tampered with during transit. Generate a DKIM public and private key pair, add the public key to your domain's DNS settings, and configure your email sending platform to sign outgoing emails with the private key.
4. Implement DMARC policy: DMARC combines SPF and DKIM authentication and allows you to set a policy for how email servers should handle failed authentication results. Create a DMARC record in your domain's DNS settings, specifying the desired policy (quarantine, reject, or none), and provide an email address where DMARC failure reports should be sent.
5. Monitor and maintain: Regularly monitor your email authentication results using tools such as DMARC analyzers or report aggregators. Analyze the reports to identify any authentication failures or potential unauthorized email activity, and take appropriate actions to rectify any issues.
