E-mail authentication key to war on spam

-mail filters have become effective at preserving our in-boxes, creating the illusion that spam has been tamed. But the bulk of spam is growing. MessageLabs said about 70 percent of all e-mail traffic as of this week, and 66 percent this year, was bogus.

Although junk- and malware-laden messages have been pushed out of sight for many computer users, they are not out of mind for those minding e-mail delivery systems, who say tackling the growing problem demands an answer to the simple question: Who's e-mailing?

That's what Microsoft and Sendmail say must be answered if businesses are to save e-mail from having its "killer app" status redesignated.
