Mail function on Live Server is Not sending Mails - php

Question

I have a website and have enabled to send mail using the By default mail function of php
My code is this
I have tested it from other posts also.. and for me it is correct.. but it is still not sending the message. Please tell me.. where is the problem
<?php
include_once './config.php';
$con=mysqli_connect(mysql_host,mysql_user,mysql_password,mysql_database);
$Roll = $_REQUEST['UserName'];
ini_set('display_errors',1);
// Check connection
if (mysqli_connect_errno($con))
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
else
{
$confirmCode = md5(uniqid(rand()));
$tbl_name1 = "temp_forgot_acc";
$orderCheck = "DELETE FROM $tbl_name1 WHERE EmailId = '$Roll'";
mysqli_query($con,$orderCheck);
$order = "INSERT INTO $tbl_name1 (EmailId,confirm_code) VALUES ('$Roll','$confirmCode')";
$result = mysqli_query($con,$order);
//if($result)
// {
// ---------------- SEND MAIL FORM ----------------
// send e-mail to ...
$to=$Roll;
// Your subject
$subject="Your Forgot Pass link here";
// From
$header = 'From: Admin <admin#test.com>' . "\r\n";
// Your message
$message="Your Comfirmation link \r\n";
$message.="http://www.test.com/test.html?passkey=$confirmCode&Email=$Roll";
// send email
mail($to,$subject,$message,$header);
// }
echo '{"data":[';
echo "{" . '"Finish":'.'"YES"}';
echo ']}';
}
mysqli_close($con);
exit();
?>
I am able to insert it in the database... but it is not sending the maill.

Try code something like this in your application:
$from = "sender id" // sender must be valid
$subject = "subject";
$message = 'mail from'.$from.'sender';
$to = "receiver id";
// send mail
$headers = 'From: <test#test.com>' . "\n";
$headers .= "MIME-Version: 1.0\n" ;
$headers .= "Content-Type: text/html; charset=\"iso-8859-1\"\n";
mail($to,$subject,$message,$headers);
and check what you have in $to value..email id must be correct.
