How to "bounce" unrouted email

[Rafael]

Unrouted email is one of the biggest sources of spam for your account. This occurs when a spammer attempts to send email to an address not found in your account (i.e. anybody@yourdomain.com). This email gets sent to your "default" mailbox filling in with junkmail over time.

You can "bounce" these messages back by accessing Cpanel>Mail>Default Address>Set Default Address>:fail:

Taking the time to set up this simple measure for your account will save you disk space and keep your "default" mailbox clean
