To Fight Spam, Google Apps Adds E-Mail Signing

DomainKeys Identified Mail (DKIM) helps prove the identity of senders.

Cnet: Google is rolling out a technology called DomainKeys Identified Mail (DKIM) to allow all Google Apps users to sign their e-mail. The technology, which has been used by PayPal and eBay since 2008, helps senders prove their identity and prevents mail from getting caught in recipients' spam filters.

At the same time, Google also debuted a tool that allows IT administrators to control whom users can communicate with via e-mail. For example, schools can use the tool to prevent students from receiving e-mail from outsiders (including spam), while still allowing e-mail from other students and teachers.
