I forgot to indicate the syntax for test.
As user bruno:

mail -s "test message" root<ENTER>
test<ENTER>
^D
Cc:<ENTER>

which I expected to receive in the local mailbox 'root' but not sent to my ISP 
smtp server which is then logically bounced back with 550 host unknow error 
becasue local domain is unknown.

Thanks for any help.
