I also seem to have problem with "appenddelete". It sure appends, just like "append", but it does not delete the messages it has moved to the existing mailbox. I have to use "prune ALL" in my script now to get rid of the messages after I moved them using "appenddelete", which has some un-nice race conditions.
appenddelete works for me. Is the source mailbox readonly? What server are you using?
