note 24720 rejected from ref.mail by victor

I tried using the mail() function, and seems to work fine in the sense that it sends out the email to the intended receipients with all the defined headers. That is not the problem for me - the problem is that whenever I run a PHP script that calls the mail() function, the script produces these 2 lines as the output on the terminal: X-Powered-By: PHP/4.0.4 Content-type: text/html Normally, this should not be a problem, but I run this script from the crontab, and whenever this script runs and outputs these 2 lines, I receive an automated notification email from my domain host giving me the output of the cron job (as if it were an error). So, I was wondering if there is any way to suppress these notification messages, which do not even provide any use here. Thanks.
