  IdMailBox (Created for use with the IdIMAP4 unit)
  By Idan Cohen [email protected]

  2001-FEB-27 IC: First version, most of the needed MailBox features are implemented,
                  next version should include a MailBox list structure that will hold
                  an entire account mail box structure with the updated information.
