One way to ensure that you get all email directed at your domain is to create a “catch-all” email address. This means any mail sent to a particular address @YourDomain.com will be seen by you. This is important for a number of reasons and can easily be done through cPanel.
In this tutorial, we’ll show you how to create a catch-all email address in cPanel.
2) Access cPanel (Go To "My Services" under the Services Menu and click on the Hosting Service under "Products & Services Then Login to cPanel Link is on the left)
3) Once in cPanel, scroll down to Email and click Default Address (first link on the second row in the screenshot below)
4) On the Default Address page, choose the desired domain from the drop-down menu and tick “Forward to Email Address.”
5) Type your Forward to Email Address on the next line and click Change.
That’s it! Any mail directed @YourDomain without an assigned email address will be directed to the forward that you just created.
