Junk E-mail Reporting Tool
The Microsoft Junk E-mail Reporting Tool version 1.0 for Microsoft Office Outlook is a neat add-in for Outlook that allows a user to report an e-mail message as junk. This kind of mechanism is already used in Hotmail.
"The Junk E-mail Reporting Tool submits e-mail to Microsoft when you explicitly choose to do so. If you receive a junk e-mail and want to report it to us for analysis, first select the e-mail in Outlook and then click the junk e-mail button on your tool bar. You will see a pop-up window asking whether you want to report the selected e-mail to Microsoft and its affiliates. When you click “Yes” to confirm that you’d like to report the selected e-mail as junk e-mail, the junk e-mail will be deleted from your Inbox and sent to FrontBridge, a Microsoft company, for analysis to help us improve the effectiveness of our junk e-mail filtering technologies."
The messages reported this way will be sent to abuse@frontbridge.com, where probably they will be used to more accurately define what is or what is not unsolicited commercial email
