A Toronto Internet service provider has launched a spam-filtering service that includes the option of having employees in India review a company’s sequestered spam for false positives: wrongfully blocked e-mails.

According to Ashok Kalle, president of Pathway Communications, more than 99 per cent of spam can be filtered by combining his firm’s recently launched NetPulse appliance with this “last look” false-positive checking service, which costs $1 per mailbox per month.

“Our customers… can either choose to tag the spam and sequester it, or drop the spam into one large folder and access it themselves, or they can have it looked at by one of our employees sitting in India,” Kalle said.

The service is designed to make spam filtering “as non-intrusive and non-intensive as possible,” he said.
