<p>"Note that with dbox the Index files contain significant data
which is held nowhere else. Index files for both sdbox and mdbox
contain message flags and keywords. For mdbox, the index file also
contains the map_uids which link (via the “map index”) to the
actual message data. This data cannot be automatically recreated,
so it is important that Index files are treated with the same care
as message data files."</p>
