it's local mail; by default there are no open port on an Ubuntu
machines toward the outside world; so no external e-mails can reach
your computer unless you explicitly open postfix to the outside world.

If a local job on a machine has an error or something, sometimes it
will generate an e-mail and send it to the account "root".  I believe
in Ubuntu this will by default get forwarded to the first user of the
system, probably you here.

>From an xterm, type "mail" to see these local e-mails.  Or simply
check the files in the directory /var/mail/
