If the message has a content that not is an attachment the decodedata() of MimeContent Class doesn't works.
Example: Outlook permits copy and paste captures from clippboard that converts it in png images as mimecontents.
I can get contents from message with menssage.GetAllContents, but i cannot save it as files because the method DecodeData() has the code:
if (this.IsAttachment == true)
I unknowkn if this is a bug or not..
