Cron Job Email Notification

Hi! So I set up postfix on my ubuntu server and it started emailing me the results of a the daily cronjobs. I'm guessing I filled in my email when I first set up the machine somewhere, but I've forgotten where. I'm wanting to change where the email goes.. for some reason I put in a group address instead of just me. Any ideas where I would set that email address? It's coming from root@servername.
