Changing your default email (also referred to as the catch-all email) account is quite easy.
You can do this from cPanel in a few simple steps.
[Note: By default, or until you change it, the default email address will be the same as your “login name.”]
Here’s how to do it –
1. Log in to cPanel.
2. Select “Default Address”.
3. Select “Set Default Email Address”.
4. Enter a desired default email address; just enter a name, (the @yourdomain part is added automatically).
5. Select “Change”.
You’ll see a confirmation box, which displays your new default email address. That’s it- done!
My Cpanel does not have a “Set Default Email Address”.so it is not possible to follow your steps
