php mail function not working

[cainam29]

need help, mail function not working...

 

here is my php mail code:

 

<?php
//for getting the variable in the URL
$WirelessRemaining= $_GET['WirelessRemaining'];
$WirelineRemaining = $_GET['WirelineRemaining'];
$date1 = $_POST['date1'];
$output= $_POST['output'];

require 'include/DB_Open.php';

 $to = "[email protected]";
 $subject = "Test, $date1";
 $body = "$output";
 
 $headers = 'MIME-Version: 1.0' . "\r\n";
 $headers .= 'Content-Type: text/html; charset=ISO-8859-1' . "\r\n";
 $headers .= "From: aaa bbb <aaa.bbb@ccc>\r\n";

 if (mail($to, $subject, $body)) {
   echo("<p>Message successfully sent!</p>");
  } else {
   echo("<p>Message delivery failed...</p>");
  }

include 'include/DB_Close.php';  
?>

this codes would have values coming from the generated report, which was performed by another php page

$WirelessRemaining= $_GET['WirelessRemaining'];
$WirelineRemaining = $_GET['WirelineRemaining'];

while is a date field from my main php page where the email button would be click to send mail

$date1 = $_POST['date1'];

and this is from the output of my report generator:

$output= $_POST['output'];

here is how i call the mail php page

$("#Email").on('click',function() {
			var date1 = $('#Date').val();
			var output = $('#report_sample.php').val();
            $.post('mail.php',{date1:date1, output:output}, function(data){
            $("#results").html(data);
            });
            return false;
		});
