short question: Is there an easy way to forward a message with the Yahoo API SendMessage method or any other way?

background: Currently I have a custom order tracking application that I built and I'm reading the email text and attachments into my system and they are reviewed from the system and appended to orders. But in some instances the emails that come in need to be forwarded as is to a manager or someone else outside of the system.

problem: I can execute GetMessage and then SendMessage with a "simplebody" but that does not preserve the inline attachments or attached files obviously. As for using "body", ComposeMessagePart is not documented well enough for me to understand how to get from my GetMessage return value to what I need to have to send this email. It makes no sense that I would have be able to retrieve a message from the Inbox but to send that exact message I'd have to download all of the attachments one by one and re-upload them.

Any advice would be appreciated.
