Most versions of cron automatically mail any output to the user,
so this would be the simplest thing to do.

It can be done, but mail(1) is actually designed as a mail
reader, so it's a stretch to do what you want.

This is incomplete.  The following is intended as a starting
point, and will need you to work out the details.

    ( echo "To: me at my.com"
      echo "From: root at your.com"
      echo "Subject: Results of the cron job"
      echo
      hostname
    ) | qmail-inject 

This creates some useful headers for the message and gives it
the output of the "hostname" command as a body.  You'd replace
that last part by the stuff you want to run.

To see what's being done, if you don't grok shell scripts, just
replace the qmail-inject with cat.
