In the cPanel forwarders option how to pipe a system default mail account?
For example if the system username is sample and the domain name is example.
Address to Forward: here a text box accepts the name and next to that is a list box which is the domain name and it is mandatory. so the email address will become sample@example.com but a system default mail id is not associated with @domainname.com i think
see the screen shot...

in that i can specify sample as the system default mail account but the list box shows the sitename.
so how to specify only the system default mail account to be forwarded to a piped program or to another email address ?
