First Login into cPanel and then click the Default Address icon.

This is where you set your default address so that all unrouted email will have a place to go.

Since we likely won't be using that address, let's set it to an email address we will be using.

Click Forward to email address.

Currently, our default address is set to our account name, meaning all unrouted emails will be stored in our main email account.

Then enter the email address you want as your default address.

Click Change.

That's it! The default address has been set.

You can always update your default address setting by returning to this screen.

The new default address setting can be seen here.
