I've been using Ihatespam by sunbelt software, not sure if you can block by IP but I know you can do it by domain. http://www.sunbeltsoftware.com/product.cfm?id=930 Always rated pretty highly by the PC Mag rags.

Does anybody have an idea of a consumer product that also does IP screening. At work I'm generally screening whole blocks of subnet's. I'd "prefer" to do that at home. We're not using citrix all the time, what do you use at home.
