Is there a setting to delete mail off of the server when you delete it from your mac? I know you can go to advanced settings and remove email from the server after a set period of time by checking the box. But, what if I wanted to keep all email on the server unless I deleted it from mail? Is there a way to do that? For example, I have an account that gets spam. I'd like it to delete it from the server as soon as I delete it on my mac. But I don't want to delete emails immediately in case I need to pull it from another device for example.
