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;

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.
