That is what this config is doing. By any chance are you using Debian linux?
This setup that I tried (badly) to explain does not deliver locally. It is the public looking MX that receives all SMTP for the domain. After postfix sends through filter.sh (which calls spamc) it reinjects it to postfix to relay to the protected server. I am sorry this mail is so unreadable. The shell script is getting chopped up.
