By default, crontab on, for example, Debian, will mail any output of a job in your crontab to that user. How would one go about disabling this functionality?

There are two main ways of doing this, as I discovered.
Either you set the MAILTO-variable to nothing at the start of the file:
MAILTO=""
or you redirect each cronjobs output to /dev/null:
<command> > /dev/null
The second having the advantage that output on stderr should still be mailed to you.

3The second solution is much better, because that way you are still notified of any problems in crontab scripts.– sleskeJul 16, 2009 at 14:23

To prevent output of both stdout and stderr use the following syntax:
<command> > /dev/null 2>&1
