                  //# don't send test message using the blast server
                  if (isset($_GET['page']) && $_GET['page'] == 'send') {
                      $this->inBlast = false;
                  }
                  $this->Helo = getConfig('domain');
          
          
        if ($GLOBALS['emailsenderplugin']) {
                      $this->Mailer = 'plugin';
                  } elseif (!$this->inBlast && empty($_SESSION['adminloggedin']) &&
