I need to change the MX record for my domain to point to the Protector Firewall for anti spam scanning.
Please goto https://dnschecker.org/mx-lookup.php and there type your domain.
Then it will show your existing MX record.
Next step is to contact your domain provider or login to their interface and change it to the new dns hostname or IP address.
After the Change is made.
Then in the Protector you goto the Email Setup > Mail Servers tab put in your domain name and the mail server IP address where it sent clean mails to.
