Looks good to me.Somewhere in the forum or over at Github, Jared (greezybacon) - one of the developers - mentioned that you can create a filter that matches for the "contains @" cases and it should work and not affect existing tickets, only new tickets, but can't find it at the moment and the second this is that the user does not get any response that his/her ticket was rejected and no tried myself, even with 2 filters etc., it is not possible - when a ticket gets rejected no other actions will be executed.
