Description

I'm using mime4j to parse messages starting from a javax.mail.Message.
Then, my application needs to store in a String the original message too, that is the "eml", I did it in this way:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
 MessageWriter writer = new DefaultMessageWriter();
 writer.writeMessage(message, baos);
 this.originalMessage = baos.toString();

Unfortunately I've seen that above code, does QP encoding so the final output is different from the original message.

But in this way, the final eml results in a different eml from the original one, so for example the digital signature is not more valid.
For example if you open the generated eml with a client like Outlook, it warns user that the digital signature is not valid.

Now, I would like to know if exists a way to, starting from an eml generated with the above code, generate the correct version, so without QP encoding.

Attached to this issue, I put an original eml and that one generated with above code, thanks

Maybe this issue is related or caused to this other #MIME4J-186 ?
