SpamAssassin Rule: PYZOR_CHECK

Standard description: Listed in Pyzor (


Pyzor is a collaborative, networked system to detect and block spam using digests of messages. It uses a fuzzy checksum technique to identify message bodies based on signatures submitted by users, or inferred by other techniques such as high-confidence Bayesian or DNSBL entries.

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 Open Source or software libre, Frank Tobin decided to implement Pyzor with a new protocol and release the entire system as Open Source and software libre.
