protected function getMailer() : MailerInterface {
  if (!isset($this->mailer)) {
    $dsn = \Drupal::config('system.mail')->get('mailer_dsn');

    // Symfony Mailer and Transport classes both optionally depend on the
    // event dispatcher. When provided, a MessageEvent is fired whenever an
    // email is prepared before sending.
    //
    // The MessageEvent will likely play an important role in an upcoming mail
    // API. However, emails handled by this plugin already were processed by
    // hook_mail and hook_mail_alter. Firing the MessageEvent would leak those
    // mails into the code path (i.e., event subscribers) of the new API.
    // Therefore, this plugin deliberately refrains from injecting the event
    // dispatcher.

    $transport = $transportFactory->fromDsnObject($dsnObject);
