Why can't I see any e-mail coming in into my mail-catcher – PHP

it’s my first time using mail catcher and I was wondering why my code runs through for sending an e-mail but I don’t see anything in my mail hog / mail catcher.

Here is how I send my e-mail

Config:

###> symfony/mailer ###
MAILER_DSN=smtp://[email protected]:[email protected]:465
###< symfony/mailer ###

These are the actual live configs, which are in my .env file

Then I shave a simple form

 <section>

                {{ form_start(form, {'attr': {'class': 'custom-form'}}) }}

                <form method="post" action="#">
                    <div class="fields">
                        <div class="field half">
                            {{ form_row(form.name, {'attr': {'class': 'form-row'}}) }}
                        </div>
                        <div class="field half">
                            {{ form_row(form.email, {'attr': {'class': 'form-row'}}) }}
                        </div>
                        <div class="field">
                            {{ form_row(form.message, {'attr': {'class': 'form-row'}}) }}
                        </div>
                    </div>
                    <ul class="actions">
                        {{ form_row(form.submit, {'attr': {'class': 'form-row'}}) }}
                    </ul>
                </form>
            </section>

            {{ form_end(form) }}

And this is how I send my e-mail

    /**
 * @var MailerInterface
 */
private MailerInterface $mailer;

/**
 * @param MailerInterface $mailer
 */
public function __construct(MailerInterface $mailer)
{
    $this->mailer = $mailer;
}


#[Route('/', name: 'app_contact')]
public function index(Request $request)
{
    $form = $this->createForm(ContactFormType::class);
    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {

        $data = $form->getData();

        try {
            $this->sendMail(
                $data['name'],
                $data['email'],
                $data['message'],
            );
            
        } catch (Exception $e) {

            $e->getMessage();


        }

        header('/');

      //  return $this->render('contact/success.html.twig');

    }



    return $this->render('contact/contact.html.twig', [
        'form' => $form->createView()
    ]);
}

/**
 * @param MailerInterface $mailer
 * @throws SymfonyComponentMailerExceptionTransportExceptionInterface
 */
public function sendMail($name, $email, $message)
{
    $sendTo = 'contact@build-yourself';

    $email = (new Email())
        ->from($email)
        ->to($sendTo)
        ->subject('Contact Email from: ' . $name)
        ->text($message);

    $this->mailer->send($email);

}

When I debug the send function it says that everything is okay and it runs, why can’t I see my sent e-mail inside my mailhog

  mailhog:
