I'm already reading exactly this document, seems to be much better place to 'plug in' my code, but the question is if after-queue messages are already 'multiplied' as one copy per each recipient, because filter reaction should be recipient-dependent. In other words, if john_doe@some-external.domain sends the message to bob@my.domain and alice@my.domain putting both addresses in To: and/or Cc: fields, users can have individual settings and the very same message should pass through for Bob, but be bounced from Alice.
