Symfony version(s) affected: 5.0.5+
Description
Happens if sending a email, and after 10 seconds (and before 100 seconds) a new email (on the same connection) is sent, then a TransportException is thrown:
Expected response code "250" but got code "451", with message "451 4.4.2 Timeout waiting for data from client.".
If sending another email an other TransportException is thrown:
Unable to write bytes on the wire.
This happens until I wait for 100 seconds.
How to reproduce
Use symfony/messenger, run message:consume and send a Email, wait for between 10 and 100 seconds then send a new Email.
I have only been able to reproduce this using Amazon SMTP server, but it might be others too.
Possible Solution
setting $pingThreshold in SmtpTransport to 10 seams to solve the issue.

Looks like it happens after #35633 was introduced.
