I have a problem with nobody!

I have been googling this to death and have many references to this, but all solutions seem to either 1 not apply 2 result in parse error The code: mail ($to, $subject, $message, $header); The error Email is sent to recipient as nobody@fqdn.com (fqdn = fully qualified domain name) I have read about a -f function. I tried mail ($to, $subject, $message, -f$header); mail -f($to, $subject, $message, $header); both result in parse error. I read about changing a php_value in my httpd.conf Couldn't find any reference. So, I turn to my friends on the php_list Any assistance would really be appreciated! Running CentOS Cpanel Exim
