Nearly all of the Internet-connected computers that send e-mail are controlled by spammers, according to companies that track e-mail reputations.

Less than 1 percent of systems that send e-mail can be deemed a good citizen of the Internet, according to Return Path, a company that compiles e-mail reputation data. Return Path collects data on 20 million Internet Protocol addresses that send e-mail, the company said Tuesday.

“The majority of e-mail out there is spam. It is coming from compromised hosts,” said George Bilbrey, general manager of delivery assurance products at New York-based Return Path, which specializes in helping companies get their e-mail delivered to in-boxes.
