Setting up mail server on a dedicated server. - repost 2

Hi, I am looking for expert who has experience on setting up server for pmta + ip rotation + dkim + spf + email signatures, + bounce or any other necessary tuning to stop my emails going to spam folder. Some plugins already installed or configured. This is a re-post project because of unfinished tasks, pls do not offer if you do not have enough experience. Only teamviewer or ammy connection accepted for server log in. Ps. I have not sent bulk emails, just 20-30 emails per day. Thank you for any offers. Server : Centos 6.4 WHM 11.38.1
