How can I set up cron so it stores its output locally for me to read with mail?

I have a cronjob setup on my machine. Sometimes, this job misbehaves. I'd like to read its output locally with the mail unix program.

If I attempt to run mail, command-not-found suggests I install mailutils, and when I do, Ubuntu starts a wonderful journey into setting up an actual SMTP server. Eeeeek!

I just want my "mail" to sit in /var/spool or whatever.

How can I achieve this?
