Trash preferences in Big Sur Mail Program
Does anyone know how to set the preferences for the Trash bin in Mail on Big Sur. I have an all trash bin, and the preferences are set to that bin, but when I delete an email I get a new trash bin appearing under the on my Mac sidebar for that account (I have multiple accounts). If I delete it from there, it moves to that all trash bin and I have to delete it again. How do I keep those other trash bins from appearing?
