I want to take a lot of old emails from Apple Mail, specify a certain date and then archive them. Fine, I can do that with MailStewardPro. BUT I can't see the point of that unless I can then delete all the original emails from Mail afterwards. The whole point is to make Mail sleeker and faster. MailStewardPro won't delete the originals - the narrator in one of their videos says as much. Neither will MailArchiver. There must be a simple way to do this. Anyone?
