I'm surprised you don't have mail. I thought it was installed by default
on breezy. And indeed I thought cron would depend on it, but I've just
checked and cron depends on postfix or mail-transport-agent.
I think I suggested earlier that you try mailing root and checking the
postfix logs. They are in /var/log/mail.log and /var/log/mail.err. Both
these files may give you a clue about what is happening to mail to root.
But it looks to me like cron/anacron is sending mail to your local root
user, but a config error is causing this to be delivered to your ISP and
not your local machine. You could send me your postfix config file and
I'll take a quick look at them, if you like. The file to send is
/etc/postfix/main.cf. It shouldn't contain anything sensitive such as
passwords, but feel free to mask these out if any are there. Can you
also remind me what is in /etc/mailname again. I'm losing track!
