A Seattle man once known as the "spam king" has been sentenced to three years and 11 months in prison for mail fraud, e-mail fraud and tax evasion.

Robert Alan Soloway was arrested last summer. Prosecutors said he made hundreds of thousands of dollars selling so-called "broadcast e-mail services" and used networks of compromised computers to send out millions upon millions of junk e-mails.

U.S. District Judge Marsha Pechman issued the sentence Tuesday. She will hold a hearing later to determine how much restitution Soloway must pay.
