Symfony version(s) affected: 4.4.16, 5.2

Description
Our system sends e-mails asynchronously using the Messenger component. Two messenger consumers are running in the background with Supervisor. We use Doctrine for our message transport and AWS SES over SMTP for e-mails. On our production system we are seeing the following error occur. This issue was already described here: #36301. A PR was merged, but we are still seeing this problem.

Symfony\Component\Mailer\Exception\TransportException

Expected response code "250" but got code "451", with message "451 4.4.2 Timeout waiting for data from client.".

After the messages fail for the first time, they will get retried. Eventually after one or two retries they do get send successfully.

How to reproduce
