Contact form auto-reply does not send

I have the same problem, and I think it has to do with this piece of code:

/**
 * Implements hook_mail_alter().
 *
 * @throws \Drupal\Component\Plugin\Exception\InvalidPluginDefinitionException
 * @throws \Drupal\Component\Plugin\Exception\PluginNotFoundException
 */
function contact_emails_mail_alter(&$message) {
  // If an email from the contact module, disable sending.
  $contact_form_ids = [
    'contact_page_autoreply',
    'contact_page_mail',
  ];
  if (in_array($message['id'], $contact_form_ids)) {
    /** @var \Drupal\contact\MessageInterface $contact_message */
    if ($contact_message = $message['params']['contact_message']) {
      $contact_form = $contact_message->getContactForm();
      $contact_form_id = $contact_form->id();
      /** @var \Drupal\contact_emails\ContactEmailStorageInterface $storage */
      $storage = \Drupal::entityTypeManager()->getStorage('contact_email');
      if ($storage->hasContactEmails($contact_form_id)) {
        // Disable sending of default mails if we have at least one email
        // set by contact_emails (regardless of whether or not it is a disabled
        // email).
        $message['send'] = FALSE;
      }
    }
    else {
      // If we don't have a contact_message object, something must have gone
      // wrong, let's disable just in case.
      $log = t('Unable to load the contact message when attempting to alter the default mailing from contact form for contact form id: @contact_form_id', ['@contact_form_id' => $message['id']]);
      \Drupal::logger('contact_emails')->notice($log);
      $message['send'] = FALSE;
    }
  }

Located in web/modules/contrib/contact_emails/contact_emails.module. It says "disable sending of default emails of we have at least one email set by contact emails".

So when I have a contact email entry here: /admin/structure/contact/manage/contact/emails
It does not matter if I fill the auto-reply in /admin/structure/contact/manage/contact.

But when I delete all emails in /admin/structure/contact/manage/contact/emails, auto-reply does work.

Sorry, my bad, this code belongs to contact_emails module, not to this one, although it is affecting this one. I already created a ticket for contact_emails: https://www.drupal.org/project/contact_emails/issues/3358232 🐛 Contact form auto-reply disabled when contact email available Active
