Wenn ich versuche, E-Mails mit der PHPMailer-Klasse zu senden, erhalte ich den folgenden Fehler: Mailer-Fehler: Nachrichtentext leer:

<?php

    include("class.phpmailer.php");

    $mail = new PHPMailer();
    $mail->IsSMTP();

    $mail->SMTPAuth   = true;

    $mail->SMTPSecure = "ssl";
    $mail->Host       = "rsb20.rhostbh.com";
    $mail->Port       = 465;
    $mail->Username   = "jobserreker+furrtexlab.com";
    $mail->Password   = "12345678a";

    $mail->From       = "[email protected]";
    $mail->FromName   = "Job Seeker";
    $mail->Subject    = $_GET['subject'];
    $mail->MsgHTML($_GET['msg']);

    $mail->AddAddress($_GET['to'],"name to");
    $mail->IsHTML(false);

    if(!$mail->Send())
    {
      echo "Mailer Error: " . $mail->ErrorInfo;

    }else{

        echo "Message sent!";
    }
?>
