1. Identify Authorized Mail Servers: Determine which mail servers are authorized to send emails on behalf of your domain. This includes your email service provider, your organization’s mail servers, and any third-party services that send email on your behalf.
2. Create an SPF Record: Create an SPF record that lists the IP addresses or hostnames of the authorized mail servers. The SPF record is added to your domain’s DNS settings.
3. Publish the SPF Record: Add the SPF record to your domain’s DNS settings. This is usually done through your domain registrar’s control panel.
4. Test the SPF Record: Use online tools to test your SPF record and ensure it is configured correctly. These tools can also help you identify any potential issues.
5. Monitor SPF Reports: Monitor the SPF reports to check for unauthorized sending attempts and to ensure that your legitimate emails are being authenticated properly.

In this record:

• v=spf1 indicates the version of SPF being used.
• ip4:192.0.2.1 authorizes the IP address 192.0.2.1 to send emails for “example.com.”.
• include:_spf.thirdpartyservice.com authorizes the servers listed in the SPF record for “thirdpartyservice.com” to send emails for “example.com”.
