A Brooklyn man was sentenced to 30 months in prison on Tuesday for sending spam e-mails to more than 1.2 million subscribers of America Online in a scheme that foiled the Internet company’s spam-filtering system.

Adam Vitale, 27, was sentenced in federal court in Manhattan after pleading guilty more than a year ago to breaking anti-spam laws. He was also ordered to pay $180,000 to AOL in restitution.

Vitale was caught making a deal with a government informant to send junk e-mails — known as spam — that advertised a computer security program in return for 50 percent of the product’s profits, prosecutors said.

“Spamming is serious criminal conduct; this is not a teenager engaging in child’s play,” U.S. District Judge Denny Chin told Vitale as he sentenced him. Vitale earlier apologized and said he had learned a lesson.
