Centos Postifx Email admin wanted

I have one server with 100 ips on it. I have postfix on it with CentOS. I need all 100 domains on 100 ips setup using postfix. Each domain must use its own IP and each ip must have its own DKIM/DK/SPF/RDNS installed so each domains mail server is seperate from each other. Nothing can be shared but the postfix process. I want to run one postfix process and have all 100 domains run off it, but each one must have its own DKIM/DK/SPF/RDNS If you know how to do this then i will hire you and pay you nicely. thanks, Chris
