    require 'PHPMailerAutoload.php';

    $mail = new PHPMailer;

    //$mail->SMTPDebug = 3;                               // Enable verbose debug output

    $mail->isSMTP();                                      // Set mailer to use SMTP
    $mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = 'leets@gmail.com';                 // SMTP username
    $mail->Password = 'private';                           // SMTP password
    $mail->SMTPSecure = 'ssl';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 465;                                    // TCP port to connect to

    $mail->setFrom('leets@gmail.com', 'tEst');
    $mail->addAddress('leets@gmail.com');     // Add a recipient

    $mail->Body    = 'Hello ,Click On the link to reset password';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
