How do I stop cron emails?

Hi,
I have a script that runs every minute.
How do I stop cron from sending me e-mails per day (1 every minute when that script runs)?
My cron:

Code:

wget -q -O - http://domain.pl/whmcs/crons/domainsync.php >/dev/null 2>&1

It also does not work:

Code:

wget -q -O - http://domain.pl/whmcs/crons/domainsync.php > /dev/null 2>&1

It also does not work:

Code:

wget -q -O /dev/null http://domain.pl/whmcs/crons/domainsync.php

 

Problem solved
