SAN FRANCISCO, CA - September 15, 2005 - The Institute for Spam and Internet Public Policy (ISIPP) said today that the newest version of SpamAssassin, version 3.1.0, includes support for ISIPP's Email Sender Accreditation Service.

ISIPP's Email Sender Accreditation Service, also known as the "IADB", for ISIPP Accreditation Database, allows ISIPP's accredited email senders to provide information about their email sending practices and policies in real time to email receivers, such as ISPs, spam filters, and enterprise mail servers. This allows email receivers to know that they can safely accept and deliver the email, because they can tell in real time that it is legitimate, wanted mail, and not spam. In the case of a spam filter such as SpamAssassin, the ISIPP information can offset or even override a negative score which the email might otherwise receive due to its containing the wrong words, or being in the wrong format.

"We're extremely pleased to have support for our IADB Email Senders Accreditation Program built into the newest version of SpamAssassin," said Anne Mitchell, CEO and President of ISIPP. "SpamAssassin is a fantastic product, used by ISPs large and small, as well as innumerable enterprise mail servers around the world. End users expecting email from senders accredited with us will now find fewer false positives, with less wanted email being accidentally blocked as "spam", and of course our email senders benefit from that as well."

Email senders who are currently accredited through ISIPP include Innovyx, eDialog, ExactTarget, CNet, MarketingSherpa, and Date.com.

"SpamAssassin is what I use - and what I recommend to others for industrial strength, server-level spam protection," said Randy Cassingham, Publisher of ThisIsTrue.com and StellaAwards.com, both ISIPP accredited senders. "The biggest complaint I get from my readers, though, is that they don't get the newsletters they've asked for (or in some cases paid for!) SpamAssassin's action will help people get the e-mail they want, without having to pay the price of getting junk they don't want. Bravo!"

SpamAssassin is an open source spam filter program, provided at no charge at SpamAssassin.org
