About the 'cur' I'd not be too sure. If you *mv* the files there from a
directory on the same filesystem, you should be fine, but if copy the
files, I'd be careful. Probably you want to mimic the maildir behaviour:

    copy the files to tmp/
    mv the files to cur/     (not sure, if new/ would be fine to,
                              because new/ is the natural place after
                              tmp/. I'm not sure, what this does to the
                              message state the client sees.)
 
    Best regards from Dresden/Germany
