How to move message to another account?

[BrentCritch]

I'm looking for the ability to move messages between IMAP accounts - for instance so I can move all newsletters to a folder under my backup account so that they don't clutter my main inbox. Is that possible with this node? I toyed with the idea of downloading the .eml as a binary file and uploading that back to the destination folder, but there doesn't seem to be a way to do that with this node.
