The Sendmail messaging integrity pilot program
Sendmail, Inc. has announced the launch of the "Sendmail messaging integrity pilot program," a public testbed for various sender authentication schemes. Included at the beginning is a free implementation of Yahoo's "DomainKeys" system.
"'Sender-based email authentication is set to change the way email
is used. Instead of focusing on filtering out unwanted mail,
organizations will need to think about filtering in the mail they
want,' said Eric Allman, CTO at Sendmail."

The Sendmail messaging integrity pilot program Posted Jun 3, 2004 20:12 UTC (Thu) by pglennon (guest, #649) [Link] An issue that this does not address is the sheer wasted bandwidth of SPAM. filtering at the corporate entity doesn't save that money. Sprint has a ( non-carrier specific ) program to filter before it hits your network, but like most systems, it's about 70-80% effective.Maybe if the carriers start offering sender-based authentication, than only the carriers have to absorb the network cost, which in theory is partially ofset by the revenue of charging for the service. I have seen scenarios where 25+% of a small business' bandwidth is spam based. For them, that could represent a significant cost.
