pygossip Python GOSSiP distributed domain reputation service Python GOSSiP library and server. As SPF is implemented, spammers will also adopt SPF. With forging under control, the next step is to track the reputation of domains. GOSSiP tracks the ratio of spam to ham for the last 1000 messages from each domain, and computes a reputation score from that that ranges from -100 to +100. It also computes a confidence score that increases from 0 to 100 with the number and freshness of the observations. It can also check with peers, and combine scores. Observations are provided by a spam filter or user feedback. Pygossip is supported by pymilter.
