Lately, I'm having to delete email trash twice - once from the iCloud trash and again from "On my Mac" trash. Both these trash "cans" are listed separately as subfolders within the Mail Trash icon. It didn't work that way with Lion and, as far as I remember, this didn't happen with ML until recently. I checked the Preferences for Mail and I don't see where there would be an option to delete from iCloud and have it gone. What am I missing?
