Feature/Application:Setting up your MX Record for Email Security Hosted Solution
After activating your Hosted Email Security service, you may receive a message to replace your current MX records settings.
For definition of MX record, please go to the link below for more explanation
When service is activated, SonicWall registers your domain name associating with our own in the Data Center. For example, if your domain name is soniclab.us, we register your domain’s (A) record which would be soniclab.us.snwlhosted.com into our block of IP addresses.
At this point, you would have to publish the new MX record that we’ve created with your ISP. In this example, system administrator sets the MX record for Soniclab.us domain with (A) record that we activated. Most ISP provides DNS management web console that allows system administrator to edit the MX record but if not please contact your ISP.
Once the change is made, it could take up to 24 hours for new MX record to propagate in DNS.
