"The Internet's premier standards-setting body is making its first attempt to develop messaging technology aimed at reducing the amount of spam," writes Carolyn Duffy Marsan in ComputerWorld (Singapore). "Having researched spam for more than a year, the Internet Engineering Task Force recently formed a working group that will develop a standard mechanism to eliminate spam that uses a spoofed sender address. 'Identifying the sender of email won't eliminate 100 per cent of the spam problem, but (it) may get 50 per cent to 80 per cent,' says Paul Mockapetris, a former IETF chair and the inventor of the Internet's DNS...
"The IETF's new working group plans to develop a DNS-based mechanism for storing and distributing information that authorises an email server to send messages from a particular domain or network. The group is dubbed MARID... MARID could be controversial, as it is expected to choose between authentication schemes backed by email giants Microsoft, Yahoo and others... Microsoft says it will submit to the IETF its Caller ID for Email Specification, which outlines a scheme for thwarting email address spoofing. Yahoo is expected to submit an alternative proposal called DomainKeys, which use digital signatures to authenticate email servers...
"Even MARID supporters say this approach is not likely to be the ultimate solution for spam. MARID only addresses spam that comes from a spoofed email address. And it will only work when email servers activate new features that would let them determine the source of email that contains spam. That's why the [Internet Research Task Force's] Anti-Spam Research Group is exploring other ways to eliminate spam..."
