Does Apple use JavaMail? At least e-mails send by Itunes Store are shown as JavaMail in my Thunderbird (according to Display Mail User Client Addon)

Let's see what headers say:

Message-ID: <11880269.1233897337799.javamail.worun@mailerp0201>

Umh, looks like JavaMail adds itself to the Message-ID. Let's have a look to the FAQ:

Q: I set a particular value for the Message-ID header of my new message, but when I send this message that header is rewritten.
A: A new value for the Message-ID field is set when the saveChanges method is called (usually implicitly when a message is sent), overwriting any value you set yourself. If you need to set your own Message-ID and have it retained, you will have to create your own MimeMessage subclass, override the updateMessageID method and use an instance of this subclass.

class MyMessage extends MimeMessage {
    ...

    protected void updateMessageID() throws MessagingException {
 setHeader("Message-ID", "my-message-id");
    }
    ...
}

So to answer my question, yes the iTunes Store mailer agent use JavaMail, and they didn't implement an own MimeMessage subclass. I wonder how (architecture, platform) and in which language iTunes store is implemented. Anybody knows?
