Overview:

A "catch-all" is used to deliver all unroutable mail that is sent to your domain to a specific address. This allows you to receive mail even if the sender has a typo in your email address.
If you manage multiple email accounts within your cPanel service for the domain, it is best to configure forwarders as using a catch-all does not save copies and only forwards the mail to the default address. 

Method:

1. Log into your cPanel hosting environment.
2. Navigate to the "Default Address" tool under the "Email" category.
3. Select the domain name you want the catch-all configured on from the drop-down list.
4. Select "Forward to Email Address" and in the fillable field enter the email address that you would like mail to be forwarded to.
5. Click the "Change" button to commit your changes.
