Yes. In the MappedUID case, it assigns a negative number when it
discovers a message on the IMAP server but no corresponding entry in
LocalStatus and UIDMapping. These 2 separate databases are a pain, I
really want to unify them in the LocalStatus.db

I have looked at the log but I can't see anything unusual. It claims it
has a new message (-2 and -1) that it needs to copy over, it then,
fetches the messages from the local IMAP and saves it to the remote
IMAP. The remote IMAP returns a new UID just fine and theoretically, we
should not have the required entries in UIDMapping. I am not sure why
that doesn't seem to be the case for you.

Sorry, I don't really know how help debugging this. I am quite busy at
work ATM.

MMh, need to look into that.
