'Catch failed recipients in Symfony/Mailer 6.x?

In want replace deprecated SwiftMailer v6.3.0 with new Symfony/Mailer v6.x. In old SwiftMailer I collect failed recipients so that I know who has not received mail.

$successfulRecipients = $mailer->send($message, $failedRecipients);

Symfony/Mailer is not working this way. How do I find failed recipients in Symfony/Mailer? Maybe with try/catch for TransportExceptionInterface but there is no example what exactly is returned.

How do I get the mail addresses which have not received the mail? Because maybe their mailbox was full or the mail was too big?
