SpamSieve Cmd-Shift-J toggles in Apple Mail for mark as SPAM or mark as good. SpamSieve uses Cmd-Control-S and Cmd-Control-G, respectively. Can KM use Cmd-Shift-J depending on whether in the InBox or Junk mailbox (I have a Smart Mailbox collecting All Junk). I’ve just resubscribed to SpamSieve after more than a year of not using it because Apple’s filtering doesn’t work well.
