But wouldn't it be in Microsoft's best interest to prevent their servers from being used to spam?
Tangent inspired by the above question: Consider this host, which sends mail from Microsoft employees:
Received: from smtphost1.microsoft.com ([131.107.3.116]) by mx.gmail.com with ESMTP id 8si3854684wrl.2006.01.27.18.04.33; Fri, 27 Jan 2006 18:04:33 -0800 (PST)
No reverse DNS. HELO smtphost1.microsoft.com, but that's the name of 131.107.1.101. So, it looks like scam mail supposedly from Microsoft. But 131.107.3.116 is in their _spf-a.microsoft.com SPF record. Oh, I get it. We use SPF or our filter misfires. Pretty risky stance for them to take with their own employees' mail.
