SpamSieve is an application that integrates with e-mail clients to filter out unsolicited mass mailings, commonly known as “spam.” Previously, most people just ignored spam messages or created simple rules in their e-mail clients to filter it out. In recent years and months, the spam problem has gotten worse. Today’s spam is harder to detect, and there is more of it. People have turned to a wide variety of software solutions to help regain control over their inboxes. This software differs primarily along two dimensions: how it identifies spam messages; and how it reduces their burden on the user.
