I noticed that the message id from Sendgrid didn't get always parsed properly. Looking into the issue I found that sometimes the format looks like
UM1N3y_WXg6h51oIppcERgorX8P9ZIaiT3653-UXj4ljGXwhich isn't matched by the current regex at https://github.com/symfony/symfony/blob/7.3/src/Symfony/Component/Mailer/Transport/Smtp/SmtpTransport.php#L159-L160This PR fixes matching all Sendgrid ids.
