[imp] imp quota

[Jf]

Hello,

I try to configure the function imp_show_quota, but nothing is show.

I have postfix

What is missing ?

My configuration:


$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) {
          $quota_html = '';
          //$imap_admin = 'admin';
          //$imap_passwd = 'password';
          // Use the following two lines instead for Courier.
           $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, 'user.' . $imp['user']);
          // Use the following line instead for Courier.
          $quota = @imap_get_quota($stream, 'ROOT');
          imap_close($stream);

          if (is_array($quota) && $quota['limit'] != 0) {
              $taken   = $quota['usage'] / 1024.0;
              $total   = $quota['limit'] / 1024.0;
              $percent = $taken * 100 / $total;
              if ($percent >= 90) {
                  $class = 'quotaalert';
              } elseif ($percent >= 75) {
                  $class = 'quotawarn';
              } else {
                  $class = 'control';
              }

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