I want my server (Verizon Yahoo) to trash and delete messages when I trash or delete them on my 5s. I have gone into my Verizon account on the phone, made sure Trash was selected rather than Archive, selected "Delete from server..."when removed from inbox"", restarted, etc. Everything else works in the account, and when I delete on the server, it is deleted on the phone. I want emails to delete from the server when I remove them from the phone's inbox. Supposed to happen, but doesn't.
