Is the site hosted on a dedicated server/VPS, or are you hosting it from an ISP's IP pool? Some ISPs reject IP pools automatically. I know AOL used to do that when I ran one of my sites from a server beneath my desk. I was using Exim and that took some tinkering to get it to work in a satisfactory way.
It's a dedicated server running in a data center so it should be a perfectly acceptable ip address.
