Envoi mail avec mailer symfony sur localhost

Bonjour,

J'essaie d'envoyer un mail via mailer symfony 5.3.10 et j'obtiens l'erreur " Connection to "localhost:1080" has been closed unexpectedly. "

mailcatcher est bien configuré car avec un script à part en local, cela fonctionne bien peu importe le port utilisé 'en changeant dans le php.ini et en démarrant sur le bon port mailcatcher)

mon mailer.yaml

framework:
    mailer:
        dsn: '%env(MAILER_DSN)%'

ma commande

<?php

namespace App\Command;

use App\Repository\UserRepository;
use App\Repository\ContactRepository;
use App\Service\ContactService;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Mailer\MailerInterface;
use Symfony\Component\Mime\Address;
use Symfony\Component\Mime\Email;

Class SendContactCommand extends Command{
    private $contactRepository;
    private $userRepository;
    private $contactService;
    private $mailer;
    protected static $defaultName = 'app:send-contact';

    public function __construct
    (
        ContactRepository $contactRepository,
        UserRepository $userRepository,
        MailerInterface $mailer,
        ContactService $contactService
    )
    {
        $this->contactRepository = $contactRepository;
        $this->ContactService = $contactService;
        $this->userRepository = $userRepository;
        $this->mailer = $mailer;
        parent::__construct();
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $toSend = $this->contactRepository->findBy(['isSend' => false]);
        $address = new Address($this->userRepository->getUserAuthorized()->getEmail(), $this->userRepository->getUserAuthorized()->getLastname() . '');

        foreach ($toSend as $mail){
            $email = (new Email())
            ->from($mail->getEmail())
            ->to($address)
            ->subject('Nouveau message de "' . $mail->getNom() .'"')
            ->text($mail->getMessage());

            $this->mailer->send($email);
            $this->contactService->isSend($mail);
        }
        return Command::SUCCESS;
    }

}

mon .env

# In all environments, the following files are loaded if they exist,
# the latter taking precedence over the former:
#
#  * .env                contains default values for the environment variables needed by the app
#  * .env.local          uncommitted file with local overrides
#  * .env.$APP_ENV       committed environment-specific defaults
#  * .env.$APP_ENV.local uncommitted environment-specific overrides
#
# Real environment variables win over .env files.
#
# DO NOT DEFINE PRODUCTION SECRETS IN THIS FILE NOR IN ANY OTHER COMMITTED FILES.
#
# Run "composer dump-env prod" to compile .env files for production use (requires symfony/flex >=1.2).

et si j'envoie via un autre port, il me dit "The "25" mailer DSN must contain a scheme."

Je vous remercie de votre aide
