Folks, Many of you have written to me over the last few months about the possibility of caching Razor signatures to avoid network latency of Razor check. We've come up with a plan and I want your feedback, specially if you are running Razor in a high- volume environment like an ISP.
As you know, the open source Razor agents support a subset of signature schemes supported by the commercial SpamNet products. The extra signatures supported by SpamNet allows for over 98% accuracy. We've extended the Razor2/SpamNet system to identify a relatively small hot set of signatures responsible for 90% accuracy. This set is designed to be "conservative", in that it has an extremely low false positive rate. 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 [EMAIL PROTECTED] with your thoughts on the design and pricing. Also, feel free to forward this mail to anyone you think would be interested. cheers, Vipul ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
