Wholesale ISP Raises Bar in Fight Against Spam

Virual ISP software offers Sender Server Validation to protect end-user.

Grants Pass, OR (PRWEB) February 7, 2007 -- Wholesale ISP visp.net (http://www.visp.net) has developed proprietary ISP software with Sender Service Validation (SSV), a new anti-spam tool that makes it more difficult than ever to infect end-users' e-mail inboxes with junk e-mail and viruses.

The new tool ─ developed by wholesale DSL provider and virtual isp, visp.net ─ significantly reduces spam in a subscriber's e-mail inbox by verifying the remote server through soft greylisting and a combination of other tools, according to Nathan Miller, visp President/CTO, who heads up the R&D team for ISP software at the company.

In both cases, these types of spam will never reach our customer's subscribers when they have SSV-enabled because SSV confirms the validity of the remote mail server with a high degree of accuracy.

Valid e-mail is routed from a sender (point A) through a valid mail server (B) to a receiving mail server (C) and then to the recipient (D). Most spammers, on the other hand, use their personal computers as points A and B and send directly to the recipient's mail server (point C), bypassing a valid sending mail server, which would not normally permit spam. With SSV enabled, visp.net's mail server detects this distinction and deliver's the message only after the sending mail server has been validated.

"More than 90 percent of spam is from a spammers' personal computer or from a system infected with a virus and sent directly to the recipient's mail server," Miller said. "In both cases, these types of spam will never reach our customer's subscribers when they have SSV-enabled because SSV confirms the validity of the remote mail server with a high degree of accuracy."
