Maybe this wasn't answered yet, because I (and maybe others?)
find this a _very_ bad idea. In todays Spam the Return-Path
is nearly almost faked and this will lead your cooporate gateway
to annoy _a lot_ of innocent people. That's why some posters
already proposed to replace your ideas with something that
does not generate bounces, e.g. Spamassassin with Scoring
(which could include DNSBLs, too).
