Press Release
RETURN PATH TO TAP INTO THE POSTINI THREAT IDENTIFICATION NETWORK TO BOOST BONDED SENDER PROGRAM
SAN CARLOS, CA, November 7, 2005 — Postini, the global leader in Integrated Message Management, today announced that Return Path, Inc. will utilize data from the Postini Threat Identification Network (PTIN) to support its Bonded Sender email accreditation service. Return Path will use PTIN to better evaluate the behavior of email senders and to judge their eligibility to become Bonded Senders.
"Postini clearly has leading email threat management technology, largely due to its real-time sender behavior analysis technology. This analysis, combined with the volume of email Postini monitors, gives a clear picture of which email senders are responsible for phishing and spam," says George Bilbrey, vice president and general manager of Return Path's Delivery Assurance Solutions. "Bonded Sender can leverage Postini's data to further improve our market leading accreditation service. This will provide a solid source of data for determining which senders are upstanding email citizens and can qualify for the Bonded Sender Program."
"Postini is in a unique position to provide instant notification of dynamically changing messaging threats at the IP connection level," said Larry Goldstein, vice president of product management for Postini. "By leveraging our position in the midst of the message flow for over 3 billion SMTP transactions a week, Postini can ensure that Return Path has real-time information on legitimate senders of email and those that are responsible for email based threats."
PTIN is a continuously refreshed repository of source IP addresses that have been observed to be engaging in unwanted or damaging actions. PTIN identifies threat behavior in SMTP connections across to all Postini customers, providing significantly better protection than real-time black lists (RBLs) against directory harvest attacks (DHAs), phishing attacks, virus outbreaks, and spam.
The Bonded Sender Program publishes a whitelist for email receivers to identify legitimate mailers. This provides an objective way to ensure only unwanted messages get blocked. Email senders in the Bonded Sender Program must pass a rigorous qualification process administered by TRUSTe and Return Path. Receivers, in turn, are able to aggressively target spam without pressure of accidentally filtering permissioned email their subscribers want. The Bonded Sender Program is the most successful and widely adopted email accreditation program. The Bonded Sender whitelist has been successfully implemented by more than 35,000 receivers representing corporations, ISPs, and universities.
