mmm kan ikke rigtigt få det til at virke har du et eksempel mere

<?php

$sql_host = "localhost";
$sql_user = "database";
$sql_passwd = "kode";
$db = "database";

$afsendernavn = "mitnavn";
$afsendermail = "test@domain.dk";
$mailemne = "Nyhedsbrev fra Bestyrelsen";

mysql_connect($sql_host,$sql_user,$sql_passwd);
mysql_select_db($db);

$res = mysql_query("SELECT * FROM users");
$check = '';
while ($row = mysql_fetch_assoc($res)) {
    $check .= "$row[username] - $row[email] <input type='checkbox' name='modtagere[]' value='$row[email]' /><br />\n";
$check .= "<input type="checkbox" name="checkall" onclick="checkUncheckAll(this);"/>select/unselect/>\n";
}
 
if(!isset($_POST['submit'])) {
    echo "<p>&nbsp;</p>
    <p align=\"center\">
    <form action='nyhedsbrev.php' method='post' onsubmit=\"return confirm('Du er sikker p&aring; du vil sende NU?');\">
    $check

  <br>
    <input type='submit' name='submit' value='Send News' />
    </form>";
} else {
        error_reporting(63);
        include('class_html_mime_mail.inc');
        define('CRLF', "\r\n", TRUE);
        $email = new html_mime_mail('X-Mailer: Html Mime Mail Class');
        $text = $email->get_file('nyhedsbrev.txt');
        $html = $email->get_file('nyhedsbrev.html');
        $email->add_html($html, $text, './');
        $email->set_charset('iso-8859-1');
        $email->build_message();

    foreach ($_POST['modtagere'] as $to)
    {
    $email->send($to, $to, $afsendernavn, $afsendermail, $mailemne);
    }

    echo "<p>&nbsp;</p>
    <p>&nbsp;</p>
    <p>&nbsp;</p>
    <p align=\"center\">
    <font color=\"#00FFFF\" size=\"5\" face=\"Arial, Helvetica, sans-serif\"><strong><font color=\"#006600\">
