1999-09-08  bertrand  <Bertrand.Guiheneuf@aful.org>

	* tests/ui-tests/store_listing.c (close_all):
	close all open folders and stores. (necessary
	for UID list saving ).

	* camel/providers/MH/mh-uid.c (mh_generate_uid_list):
	fix: store UID list in CamelMHFolder object.

	* camel/providers/MH/camel-mh-folder.c (_open):
	read or create UID list.
	(_close): save UID list.
