Catch "413 Request Entity Too Large" error

[zhil]

When you send too large email - you get error in logs.
How can it be catched correctly in code?

Sample code

$message =
            (new \Swift_Message('app:test:email'))
                ->setTo('[email protected]')
                ->setFrom($this->mailerSenderEmail, $this->mailerSenderName)
                ->setBody('test', 'text/plain');
        $message->attach((new \Swift_Attachment())
            ->setFilename('test.pdf')
            ->setBody(str_pad('', 30000000, '1'))
        );

        $result = $this->mailer->send($message);
        $output->writeln('Done! - '.$result);

Since Symfony now have improved his mailer component, I suggest to take a look at https://symfony.com/doc/current/mailer.html#using-a-3rd-party-transport to see if it fits your needs.

Otherwise, I think you can just get an error from the event Swift_Events_SendEvent::RESULT_FAILED but no details attached.
Hope this helps a bit.
