Microsoft Offers Tools to Spamming ISPs

Posted by Zonk on from the pork-checking-tools dept.

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."

    Judging from the logs of my mail filters, about 2% of the mail that is marked up by SA as spam comes from @hotmail.com addresses. Thursday, for example, my filters saw 21,863 messages that were marked as spam, and 356 of those have @hotmail.com addresses.

    When you look at where these messages are coming from, though, and compare them to the IPs hotmail uses for outgoing smtp... I don't actually see any messages that really came from them--they are almost entirely forged addresses.

    Not that I have any love of MS/Hotmail, just sayin'.
