CNET reports that Microsoft Chairman Bill Gates has sent a letter to the US Senate Committee on Commerce, Science, and Transportation outlining the official Microsoft line on spam.

The committee hearing was attended by the Vice Chairman of AOL, Brightmail's CEO, the Executive Director of EPIC (Mark Rotenberg) , and a couple of folks from the advertising industry.

Links to most of the testimony are on the site (at least the prepared remarks), although I can't find a copy of Mr. Gates' letter.
