Mailshell Incorporates Postiva Trusted Sender Technology, Building Trust-Based Email Infrastructure to Fight Spam

Mailshell Becomes First Spam Filtering Email Client to Incorporate Trusted Sender

SAN FRANCISCO, CA - August 22, 2002 - TRUSTe and ePrivacy Group today announced that Mailshell, a leading provider of anti-spam software, has integrated Postiva™ Trust Stamp technology into its web-based email client and SpamCatcher™ software. By offering customers an additional way to distinguish legitimate commercial email from spam, Mailshell's SpamCatcher™ software and email client are the first to be certified as compliant with the Postiva™ Trusted Sender Program - a cryptographically secure way for consumers, ISPs, spam filters and email clients to distinguish wanted and trusted email from spam. Postiva™ Trusted Sender is a joint program of TRUSTe, the independent non-profit organization best known for its leading privacy seal and certification program, and ePrivacy Group, a provider of trust technology and services.

Email problems today range from outright spoofing of legitimate companies to fraudulent gathering of personally identifiable information, from spreading viruses masked as security fixes to accidental flushing of important email into the spam bucket. With today's announcement, when a user of Mailshell's email client receives an email with the Postiva Trusted Sender Stamp it will have a special symbol so that they easily identify it as trusted mail.

"Spammers intentionally emulate legitimate commercial email and masquerade as legitimate companies. Incorporating the Postiva™ Trusted Sender program into our email client and SpamCatcher™ software provides an additional way for users to distinguish between legitimate commercial email and spam in disguise," said Eytan Urbas, vice president at Mailshell. "This represents the first time Mailshell has relied on a third party to authenticate senders' legitimacy-partnering with TRUSTe and ePrivacy Group is a natural fit for us."

ePrivacy Group's Postiva™ Trust Stamp technology enables real-time verification that an email message is authentic and sent by a legitimate Postiva™ Trusted Sender in good standing. Mailshell has embedded this cryptographically secure technology into its email client and SpamCatcher™ software to enable it to recognize and verify Postiva™ Trusted Sender email, ensure its delivery and alert the recipient as to its validity with a special icon. Email sent by Postiva™ Trusted Sender certified companies assure the recipient that the message is:

"Nearly half of all consumer privacy complaints made to TRUSTe are email-related," said Fran Maier, TRUSTe's Executive Director. "Establishing trust in email requires a combination of technology, industry best practices, third-party oversight and dispute resolution. Postiva™ Trusted Sender is critical to protecting email for consumers and responsible businesses."

"The problems with email have gotten so bad that trust is no longer an option, it is a necessity," said Vince Schiavone, chief executive officer of ePrivacy Group. "Rather than focus on penalties to discourage spam, Postiva™ Trusted Sender raises the bar for wanted and trusted email, securely conveying trust in a cryptographically armored seal that is backed by TRUSTe, the leading non-profit trust authority on the web."

"Since its inception, Mailshell has been driving innovation in the fight against spam. By bringing trust and intelligence to email, our technology and the Postiva™ Trusted Sender program are a perfect complement to filtering technologies like that of Mailshell's SpamCatcher™," said Schiavone.
