IBM has introduced a stop-gap sender authentication technology, dubbed FairUCE. It is stop-gap because other, more robust, sender authentication technologies such as Sender ID, SPF, and DomainKeys are still in development. These better technologies will require domain acceptance and implementation, which will require vast changes in the way current emails are published. Until then, there is FairUCE. IBM says that the new technology aims to stop the practice of “spoofing” the sender’s email address. “Spoofing” is the technique of hiding one’s sent address so the email seems to originate from another email address. Huge amounts of spam are sent out each year from compromised users’ computers, also called “zombies.” Computers infected with viruses, which go about setting up smtp engines (engines used to send emails), send out “spoofed” emails that appear to be sent from people on the infected user’s address book. FairUCE aims to stop that by implementing an “authorized” and “unauthorized” system that is generated from blacklist and whitelist of email addresses. If you are wanting some more of the technical details, visit the FairUCE link above for more information.
