I'd like to use razor-check as well on my servers, is it possible to have a server on one of my own boxes or am I forced to use public servers? Haven't found any docs around this.
Vipul made a post a few months ago about the idea of setting up a Razor caching plugin for SpamAssassin. It sounds like what you'd need, and while there haven't been any follow-ups on the mailing list, it's possible they may be working on it. Or they may not have gotten enough response.

"As regards to Razor2, here's the idea: We can develop a plug-in to SpamAssassin that keeps an up-to-date hot set of Razor2/SpamNet signatures on the local machine, has support for all signature schemes and can identify upto 90% of spam before it goes through the rest of SA checks. The local Razor2 cache would be extremely fast (able to process 10s if not 100s of messages/second), and the cache would be less than 20 Mb in size. In effect, it will increase both accuracy and throughput of a SpamAssassin spam filtration setup.
"If enough people are interested, we would provide this as a commercial service at a nominal cost. If you are interested, please send me email at <removed> with your thoughts on the design and pricing." (His email address is in the archived copy.)
