You have two options.

Redirect STDOUT and STDERR to somewhere in your job, for example:

0 1 * * * /path/to/job.sh > /dev/null 2>&1

Or set at the begining of your cron definitions:

MAILTO=""

>root@my_domain

You have to remove the root@my_domain part from the cron line or from the script as above.

Otherwise, please post the exact lines from the script/cron.

As Ivan stated above, put 'MAILTO=""' on the first line of the crontab, that work for 1 or 36565 entries...

--------
MAILTO=""
* * * /bin/test.sh
* * * /bin/blah.sh
etc
etc
