Razor (still running BTW) and Razor2 are open collaborative filtering anti-spam services.
razor-agents (both Razor and Razor2 versions) is a software package of open-source tools written in Perl for interacting with the Razor and Razor2 service. SpamNet in the service sense is an equivalent term to Razor2, as the network of signatures and meta information is identical. However, in the client sense SpamNet refers to a set of commercially improved and supported set of software, plugins and addons that interact with the service, while Razor2 in the client sense generally refers to the aforementioned open-source razor-agents. Cloudmark is a commercial company formed by myself and the author of Ricochet and Razor, Vipul Ved Prakash, to carry forward our ideas and work around next-generation anti-spam systems. Our goals include (among others) maintaining the current openly available service, providing a commercially supported service and improved software applications (SpamNet), developing new filtration technology (new SpamNet algorithms, Authority) and new applications of it, and of course building a good business around it all. The Razor2 service software backend is not currently publicly available and by our current plans we do not anticipate changing this; however as explained access to the service and its network of information is open to all. If you're interested in running your own collaborative system internally, I suggest you seek out one of the various Razor2 clones. Being derived from the ideas behind Razor and Razor2 they are all practically identical (with minor philosophical variances regarding network protocol, information sharing between disparate servers, etc.), but they by no means have the sort of userbase critical mass that is the most important aspect of any effective collaborative filtering system, and which is of course something that Razor2/SpamNet enjoys. As far as your comments about support and response times, the origins of your unwillingness to rely on Cloudmark for commercial support are unclear to me. Vipul and I, and the rest of our dedicated team work very hard to make everything the best it can possibly be for everyone, but we are still a relatively small company and thus spend more time supporting people who pay for that support than people who don't. This in no way implies that we undervalue or disregard the Razor2 community when it comes to support and quality of service; this is just a business reality and is one of many reasons the service remains available to everyone in the first place. If you have any questions regarding Cloudmark or commercial SpamNet support, please respond to me off-list (as it would be off-topic) and I can get you in touch with the right people.
