I have certain Smart Mailboxes in Mail.app (Mountain Lion, Version 6.3 / 1503) which help me find invoices for my tax declaration. I only need them once a year and would like to archive them for the other 50 weeks, because they clutter my mailbox list.
I could edit the rules and note down the search criteria, re-creating the lists once a year ... but I am looking for an elegant solution.
Is there something like Smart Playlist Management (app that exports the smarts of Smart Playlists for iTunes) ... only for Mail.app? Any idea (App, Terminal, workflow) is greatly appreciated.
