How Do I Add an SPF Record in WordPress?

Adding an SPF record in WordPress is fairly easy. First, go to the DNS settings in your hosting control panel and add your domain name (or hostname) to the list of allowed IP addresses.

Next, go to the DNS settings for your WordPress site and add your domain name (or hostname) to the “Primary DNS” section. Finally, add the following line to your WordPress site’s wp-config.php file:.

define(‘WP_DNS’, ‘your_domain_name.com’);

That’s it! Your site will now use the IP address that is listed in the “Primary DNS” section and will also be protected against spam by using SPF records.
