Called when user lists subfolders.

None  

object.ListFolders Owner, User, ParentFolder

The ListFolders Method syntax has these parts:

NOTE: This method is called only if you implemented IwodImapNotify interface in your application, and wodImapServer1.Notification property has received reference to instance of your implementation.

Before doing anything else, client will usually request to receive listing of all available folders (mailboxes) for the user. Once he requests that (and each subsequent time too!!) this notification method will be called. Here, you should:

1. Populate ParentFolder with the list of available folders (use User.Folders or Folder.SubFolders property to do so)

2. Check if new folders are available and add them to the collection

Second option may not be so much important - it will happen only when folder is added from external source, and if you implement first option properly, each time new session is opened user will receive folder list properly.

Pay special attention to folder UIDs!! Immediately after you call Add method to add new folder to the collection, you should set folder's UID property which should be preserved among sessions!

If ParentFolder is NULL (Nothing in visual basic), that means that user requested to receive list of root folders. If so, instead of using Folder.SubFolders property to populate folders, use User.Folders property instead.
