Use a nice switch statement and use the new enum values.

2001-06-18  Jeffrey Stedfast  <fejj@ximian.com>

	* component-factory.c (destination_folder_handle_drop): Use a nice
	switch statement and use the new enum values.

	* mail-callbacks.c (list_add_addresses): Now takes a hash table of
	already-used-recipients so that we don't get duplicates.
	(mail_generate_reply): Pass in a rcpt_hash argument to
	list_add_addresses(). These changes fix bug #1639.
