Symfony version(s) affected

6.1.0

Description

In #33967 multiple Mailer Transports were adapted to use $sentMessage->setMessageId(<final Message ID>);.
Among them SesApiTransport and SesHttpTransport but SesSmtpTranspor was not: It still provides the original Message-id (set by Symfony itself).

Since symfony/mailer is often used to abstract transport-specific logic it may easily result in errors where the return value is not the expected one. (In my case I need to check for actual deliverability against AWS SNS service what can only work if I stored the AWS-issued Message-ID)

How to reproduce

MAILER_DSN=ses+smtp://foo:bar@default?region=eu-west-1

$mailer->send($message);
echo $mailer->getMessageId();

Possible Solution

As per https://docs.aws.amazon.com/ses/latest/dg/troubleshoot-smtp.html
The Message-Id is returned as part of the 250 Ok response to the DATA SMTP command.
