It cannot safely remove a maildir because it has no way to stop other tools from delivering mail while mutt deletes it. The only one who has the power to stop delivery and do safe removal is the user. The same counts for MH folders. Removing empty mbox/mmdf files on the contrary is atomic and can be safely done by mutt. Rocco
