    All e-mail is handled by a set of rules that determines how messages get from one point to another. David Brussin, cofounder and chief technology officer of TurnTide (recently acquired by Symantec), turned those rules against spammers by building a router that examines the content and source of messages passing through it. When Brussins router identifies a computer thats sending spam, it reduces the number of messages that computer can send out. According to Brussin, companies using the TurnTide router see spam drop by about 90 percent.
