The only way to know that a message was sent BCC is if the envelope recipient isn't listed in the headers. Do that and you discard all the mail that comes from properly configured mailing lists and "undisclosed recipient" headers. Filter after address rewriting and you lose a whole lot more mail than that. How about the root issue? You either got an "always BCC" configured that you don't want or a specific class of Spam that can probably be handled in a better way. Which is it? Chris
