Outlook Junk Mail Filter Automatically Screened Ballmer Newsletter

Here’s an interesting spam-filtering result. I signed up for a subscription to the Microsoft Executive Emails. Today, Steve Ballmer sent me an email on “Managing IT for Business Value,” a topic that, as many of you know, is one of my major interests.
However, I only found it when I took a look at the messages the Outlook 2003 automatic junk mail filter routed into the “Junk Mail” folder. An oops or a commentary?
To me, yet another example of how spam solutions may become as big a problem as spam itself. How do I know that I’m seeing all the email that is being sent to me that I want to see? The simple answer: I don’t.
