I'm trying to open my email, but suddenly three days ago I started getting text: "There is not enough disk space to download new messages. Try deleting old mail, emptying the Trash folder, and compacting your mail folders, and then try again." The problem is, I can't do anything to it anymore, Inbox doesn't show any messages at all, the trash is not opening and any of the folders that show some messages and if I try to delete them, gives me this same text, so what to do? The whole email is locked down.
