      'smtp_port' => 465,
      'smtp_user' => '[email protected]',
      'smtp_pass' => 'correo',
    
     );

      //Load email library
      $this->load->library('email',$config);


      $this->email->from('[email protected]', 'Foreigner');
      $this->email->to('[email protected]');
      $this->email->subject('Visitor');
      $this->email->message('Testing the email class.');

     if($this->email->send()){
       echo "your email was sent";
