The Mountain View, Calif., antispam appliance maker on Tuesday plans to announce "Predictive Sender Profiling" as its latest technique to combat junk email. Filtering email is more effective by profiling messages and senders on the fly than by just looking up a reputation score in a database that's based on past behavior, said Stephen Pao, vice president of product management at Barracuda.
