GMX contact form - php

Question

I'm trying to create a simple SMTP-contact form with the help of phpMailer for my homepage but it's not working. It should forward the information of the fields "name, mail, subject, message" to my mailbox (in this case "name, mail, subject, message"). The input fields are also named "name, mail, subject, message" in my html code.
Can anyone tell me what I'm doing wrong? Thanks for any advice.
<?
require('class.phpmailer.php');
require('class.smtp.php');
$mail = new PHPMailer();
$mail->CharSet = "utf-8";
$mail->IsSMTP();
$mail->Host = 'mail.gmx.de';
$mail->SMTPDebug = 0;
$mail->SMTPAuth = true;
$mail->SMTPSecure = "ssl";
$mail->Port = 465;
$mail->Mailer = "ssl";
$mail->Password = "****";
$mail->Username = "test#gmx.com";
$mail->SMTPAuth = "true";
$mail->FromName = $_POST['name'];
$mail->AddAddress = $_POST['mail'];
$mail->Subject = $_POST['subject'];
$mail->Body = $_POST['message'];
if(!$mail->Send())
{
echo 'E-Mail not send.';
echo 'Mailer error: ' . $mail->ErrorInfo;
}
else
{
echo "<h5>" . 'Thanks for your message' . "</h5>";
}
?>

The error message says you are missing the recipient address, you have to add one using:
$mail->AddAddress("youemail#youremail.com", "Your Name");
//Your Name is optional. so alternatively you could do:
//$mail->AddAddress("youemail#youremail.com");
The part of the code you reference $mail->Username = "test#gmx.com"; simply sets the username for authenticating with the SMTP server, not the recipient address.
