Problema para enviar correo electronico utilizando phpMailer

Código PHP:

$mail = new PHPMailer();  
$mail->IsHTML(true);  
$mail->IsSMTP();  
$mail->SMTPAuth = true; // enable SMTP authentication  
$mail->SMTPSecure = "ssl"; // sets the prefix to the servier  
$mail->Host = "smtp.gmail.com"; // sets GMAIL as the SMTP server  
$mail->Port = 465; // set the SMTP port for the GMAIL server  
$mail->Username = "micuenta"; // GMAIL username  
$mail->Password = "mipassword"; // GMAIL password  
$mail->From = "[email protected]"; // "[email protected]";  
//$mail->AddReplyTo = "[email protected]"; // Reply  
$mail->FromName = "Mr.Weerachai Nukitram";  // set from Name  
$mail->Subject = "Test sending mail.";  
$mail->Body = "My Body & <b>My Description</b>";  
  
$mail->AddAddress("[email protected]", "Mr.Adisorn Boonsong"); // to Address  
  
  
//$mail->AddCC("[email protected]", "Mr.Member ShotDev"); //CC
