How does Katharion determine which messages are spam?
Katharion employs an extensive range of tests on incoming messages to detect spam. These include traditional, widely used approaches for spam detection such as message authenticity checks, header analysis, message signature analysis, an artificial intelligence Bayesian engine, databases of domain names and addresses used by spammers, and whitelists and blacklists. Katharion has also developed advanced, industry-leading techniques such as real-time message source analysis, graphics analysis, and user-based message profiling.
