A Virginia software developer has pleaded guilty to charges related to creating and marketing software designed to send bulk commercial e-mail messages, in violation of the U.S. CAN-SPAM Act, the U.S. Department of Justice said.

David S. Patton, 49, of Centreville, Virginia, pleaded guilty Tuesday to aiding and abetting violations of the CAN-SPAM Act committed by spam kingpin Alan Ralsky and Scott Bradley, both of West Bloomfield, Michigan, and other spammers, the DOJ said.

Under the terms of his plea agreement, Patton faces up to six years in prison, a fine of US$3,000 and the forfeiture of $50,100 in proceeds for the sale of his software. Patton pleaded guilty in U.S. District Court for the Eastern District of Michigan.

The CAN-SPAM Act, passed by the U.S. Congress in 2003, prohibits sending commercial e-mail messages with false sender information and with inaccurate subject lines. It requires the senders of unsolicited commercial e-mail to provide working opt-out mechanisms and include their physical addresses in the e-mail.

From January 2004 to September 2005, Patton and his company, Lightspeed Marketing, developed and sold customized software products that allowed users to send large volumes of spam e-mail at high speeds and disguise the true origin of the e-mails from recipients in order to evade antispam filters, blacklisting and other spam-blocking techniques, the DOJ said.

Patton, in his plea agreement, acknowledged that he designed the Nexus software package to enable users to insert false information into the headers of the spam e-mails it sent, the DOJ said. Patton designed Proxy Scanner to enable users to make use of third-party proxy computers to relay or retransmit spam e-mails and disguise their true origin.

Patton sold both Nexus and Proxy Scanner to Ralsky and other customers, knowing that the two software programs would be used to commit violations of the CAN-SPAM Act, the DOJ said. Patton also provided ongoing support and product updates to his Nexus and Proxy Scanner customers with the intent to assist them in violating the CAN-SPAM Act, the agency said.

Patton is the 12th defendant charged in connection with the spam e-mail operation run by Ralsky from January 2004 to September 2005. Ralsky, Bradley and six other defendants have pleaded guilty to CAN-SPAM-related charges and other offenses.
