collaborative, networked system to detect and block spam
Pyzor is a collaborative, networked system to detect and block spam using identifying digests of messages. Pyzor initially started out to be merely a Python implementation of Razor, but due to the protocol and the fact that Razor's server is not Free Software, I decided to Pyzor should be based upon a new, lighter, more language- independent protocol.
