have you had a look at postfix postscreen featue?
http://www.postfix.org/POSTSCREEN_README.html
I recommend to implement ip based blocklists via postscreen.
This is a LOCAL blacklist. I will probably move it to DNS based
eventually where it could be used by postscreen but for now it's in
testing. The listings in it are relatively short lived. The idea is to
catch new spam sources quickly before they are listed on a major DNSBL.
The list comes from emails reported by a few TRUSTED users (even then
certain hosts are excluded). After a few hours the listing expires
giving time for them to be listed elsewhere or to fix the issue.
