odoslanie mailu po vyplneni formularu

ahojte snazim sa vytvorit formular ktory ked vyplnite tak udaje z neho sa poslu mailom, s nette len zacinam cize sa v nom moc nevyznam, v presenteri som vytvoril toto :

protected function createComponentPostForm() {
    $form = new Nette\Application\UI\Form;
    $form->addText('from', 'od koho:');
    $form->addText('to', 'pre koho:')->setRequired();
    $form->addTextArea('content', 'Obsah:')->setRequired();
    $form->addSubmit('send', 'Ulozit a publikovat');
    $form->onSuccess[] = $this->postFormSucceeded;

    return $form;
  }

  use Nette\Mail\Message;

  public function OdosliMail($form) {
    $mail = new Message;
    $mail->setFrom($form->from)
      ->addTo($form->to)
      ->setSubject('mailik')
      ->setBody($form->content);
      return ($mail);
      }

  use Nette\Mail\SendmailMailer;
  public function Poslat($mail) {
  $mailer = new SendmailMailer;
  $mailer->send($mail);
  }

no a hadze mi error App\Presenters\HomepagePresenter cannot use Nette\Mail\Message – it is not a trait
ale myslim si ze tie moje funkcie su blbosti
