I am about to delete a gmail account that has been my main account for years. When I delete that account going through Google, with the smart mailbox for that account also be deleted in my Apple Mail? I looked in that folder today and didn't realize it has saved almost all email over the years. I had the fold hid so I didn't know. Now that I am deleting that account, I'd like to keep that smart folder as a library of all my past emails.
