I've done this, and then I took things a step further: What *I* have done (because I can), is configure rejection of both domains AND cidrs at the Postfix level, putting REJECT's in both /etc/postfix/access and /etc/postfix/cidr.clients. (I use *REJECT* for a reason: I figure if these idiots are going to make trouble for me, I'll make trouble for them -- eg now they will will get reject messages. Also when the addresses are from legit mail servers, the admins there will get a wake up call and presumably do something -- I have discovered that there is really little point in sending anything to the [so-called] 'abuse' addresses.) I've also configured mimedefang and spamassassin to *reject* spam at the Postfix as well.
