Rewrite postfix to include this.

What you are advocating is to alter the way that RBL works, and then
persuading someone else to host such a list and to administer it and
then also take the flak when some gets wrongly included because some bad
actors decided to get them blacklisted. None of that works right now. 
You could use procmail or spamassassin to impliment all of this on your
own machine trivially, but you would rather someone else do it for you.
Am I getting your position correctly?
