i have tried to set message-id with this code

```
use Laminas\Mail\Message;
use Laminas\Mime\Message as MimeMessage;
$message = new Message();

$message->getHeaders()->clearHeaders();

```

$message-\>getHeaders()-\>addHeaderLine(‘Message-ID’, ‘[generate.random@mydomain.com](mailto:generate.random@mydomain.com)’);

and i got this message raw from my email  
Message-ID: [5e88a6d1.1c69fb81.2faa8.789fSMTPIN\_ADDED\_BROKEN@mx.google.com](mailto:5e88a6d1.1c69fb81.2faa8.789fSMTPIN_ADDED_BROKEN@mx.google.com)
