I have something similar called "cmail", which sends mail via the mailx
command. Feel free to use/modify as needed.

I've been using a simple Perl script called "mailif". You run your cron
job like this:
0 * * * * /path/to/script 2>&1 | /path/to/mailif -s "Cron output"

mailif detects empty output or just a single dot and does not send the
email. It passes all its arguments to /bin/mail.
