Microsoft Offers Tools to Spamming ISPs

Michael writes "Computer Business Review reports that 'Internet service providers curious to know how much spam they are sending Hotmail users will be able to get detailed reports on the topic, courtesy of a service Microsoft launched in beta yesterday.' Microsoft's new Smart Network Data Services, a part of the larger MSN Portmaster initiative, allows the owners of IP blocks to view reports on the volume of email being sent from their networks to Hotmail users, and see how much of that email is being flagged as spam."
