IBM attacks spam

We can get eight out ten says Big Blue

COMPUTER MEGALITH IBM has released a test anti-spam product that it says can kill eight out of ten spam.

A Big Blue spokesman said that the software will fill the gap until better sender-authentication schemes, such as Sender ID, SPF, or DomainKeys get off the ground.

FairUCE (Fair use of Unsolicited Commercial E-mail), is posted on IBM's alphaWorks section here.

AlphaWorks is where IBM shows off its under-construction projects. Unfortunately end users can't use the software yet, although mail administrators can.

It stops spam by verifying sender identity instead of filtering content. According to IBM it can stop the vast majority of spam without the use of a content filter and without requiring a spam folder that needs to be updated.

IBM claims it removes spoofed addresses, phishing, and even many viruses with a few cached DNS look-ups and a couple of if/else statements.

FairUCE looks for a relationship between the envelope sender's domain and the IP address of the client delivering the mail, using a series of cached DNS look-ups. If such a relationship cannot be found, FairUCE attempts to find one by sending a user-customisable challenge/response. This alone catches 80 percent of UCE and rarely challenges legitimate mail. µ
