A quota report question

[Gregorio Faraldo]

Hi List
I also have the same problem I cannot make work the function imp_show_quota 
from the conf.php file 
I have installed the version 3 of IMP and 2 of the HORDE 
I have also the last version of courier-imap and i am sure i have the 
vpopmail wirh quota support
I have the maildirsize file in the Maildir
but i cannot see the status report in the mailbox page

That is my configuration file
// See the 'imp_show_quota' function below for an example.
$conf['hooks']['quota'] = 'imp_show_quota';

/* Gets the quota usage from the imap server. $imap_admin &
 * $imap_passwd must be set to fit your own settings. This works
 * with the Cyrus imap server and the Courier imap server > 1.3.12.
 * Note the necessary changes for the Courier server in the comments.
 */
if (!function_exists('imp_show_quota')) {
    function imp_show_quota ($imp) {
          $imap_admin = $imp['user'];
          $imap_passwd = Secret::read(Secret::getKey('imp'), $imp['pass']);
          $stream = @imap_open(IMP::serverString(), $imap_admin, 
$imap_passwd, OP_HALFOPEN);
          $quota = @imap_get_quota($stream, 'ROOT');
          imap_close($stream);

         if (!empty($quota)) {
             $taken   = $quota['usage'] / 1024.0;
             $total   = $quota['limit'] / 1024.0;
             $percent = $taken * 100 / $total;

             echo '<table width="100%" border="0" cellpadding="0" 	           
             cellspacing="0"><tr><td class="item"><table
             echo sprintf("%.2fMB / %.2fMB  (%.2f%%)", $taken, $total 
$percent);
             echo '</td></tr></table></td></tr></table>';
         }
     }
}

?>
