[KK Kong]

I keep geting error message:

Warning: mail(): "sendmail_from" not set in php.ini or custom "From:" header
missing in D:\Inetpub\wwwroot\php\sendmail.php on line 11

php.ini:
sendmail_from = [EMAIL PROTECTED]

sendmail.php:
<?php
mail("[EMAIL PROTECTED]", "My Subject", "Line 1\nLine 2\nLine 3",
"From: [EMAIL PROTECTED]");
?>

Can anyone help with this problem? thanks a lot!
