我目前在我的项目中使用Symfony Messenger。我用它通过MessageBox发送邮件
文件如下：

<?php

namespace App\MessageHandler;

use App\Entity\Dossier;
use App\Message\SendEmailMessage;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\Mailer\MailerInterface;
use Symfony\Component\Mime\Email;
use Symfony\Component\Messenger\Handler\MessageHandlerInterface;

class SendEmailMessageHandler implements MessageHandlerInterface
{
    /** @var EntityManagerInterface */
    private $em;
    /** @var MailerInterface */
    private $mailer;

    public function __construct(EntityManagerInterface $entityManager, MailerInterface $mailer)
    {
        $this->entityManager = $entityManager;
        $this->mailer = $mailer;
    }

    public function __invoke(SendEmailMessage $message)
    {
        $email = (new Email())
        ->from('[email protected]')
        ->to('[email protected]')
        ->subject('test')
        ->html('test');

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

}

这是一种通过Messenger跟踪邮件以从smtp服务器或类似的东西获得响应的方法吗？我想向用户显示邮件是否使用Messenger发送
