You're right, the "KMail Mail Folder" resource is the one I needed. I can now see all the folders under ~/Mail. Thank you very much, Ingo - I was tearing my hair out over this issue, so you've saved me from going bald.

One further question. I've added an IMAP account for reading new mails - that works fine. However, I can't find any way to remove an unwanted "Local Folders" resource which insists on showing in KMail's folder list, and which I will never use (outbox, sent-mail and trash all live under ~/Mail). Can this resource be removed or hidden somehow?
