ok kindly do this ( for debugging purposes only )

find

foreach($_POST['list'] as $to) {



mail($to, $subject, $message, "From: $from");



}

replace with

foreach($_POST['list'] as $to) {



echo ("emailing $to");



}

this ofcourse will not send the mails but will print out its sending them ...
If it did print the emails as emailing , then the problem will be in mail() function as in ur host configuration (we'll get to that if thats the problem)

if that didnt print output, trying removing the whole three lines and replace with

echo "nothing";
