Apache SpamAssassin is a widely used platform that incorporates advanced statistical techniques to score incoming messages. The same tactics that are applied to detecting fraudulent reviews on travel and e-commerce sites can work in spam analysis as well. When you mark a message as spam, it goes into a hopper with millions of messages that others have flagged. Algorithms churn through these messages to find similar characteristics, such as word proximity or misspellings, that show up frequently in spam.
Cloud computing is also changing the rules of spam filtering by making more powerful filters available to a broader audience at lower cost.
