Is it possible to filter addresses in the CC field but not in the TO field?

You can

  • Create a new rule
  • Choose Start from a blank rule -- check messages when they arrive
  • On the next 'conditions' page, choose Where my name is in the To box
  • Click next
  • Now choose Move to a specified folder and choose the folder

Create another new rule just the same, except choose Where my name is in the Cc box
