\&\s-1MH\s0 type message folders use one dedicated file per folder-directory to list
special tags to messages in that folder.  By doing this, mail agents may
avoid parsing all the messages, which is very resource consuming.

Labels can be used to group messages, for instance to reflect which
messages have been read or which look like spam.  Some labels are
predefined, but more can be added without limitation.

Fatal error: the specific package (or one of its superclasses) does not

related classes do implement this method however the class at hand does
not.  Probably you should investigate this and probably inform the author
of the package.
