Please edit this cron to not send mail to root@?

I have a cron as user www-data to import from webserver logs like so:

===

  • 2 * * * /var/www/piwik/misc/log-analytics/import_logs.py /home/degenaro/ducc/ducc_runtime/logs/webserver/* --idsite=1 --url=http://uima-ducc-demo.apache.org/piwik > /dev/null
    ===

The system administrator complains:

===
Can you please edit this cron to not send mail to root@ ? It does us no good to see these errors and just add more noise to our already busy inboxes.

I hunted with grep for where such messages may be generated without success. Can you suggest how I can prevent mail to root?

Thanks.

Lou.

Answer is: use MAILTO=user@my.com in crontab.
