[Dshield] Odd emails from apparently MS..

I've been getting them for several months in my Yahoo mailbox. Looks exactly
like something from Microsoft. Headers, IP's, everything. The average user
probably wouldn't know not to open them. These things come in so frequently
my Yahoo box fills up about every other day. These emails are some of the
few virus-infested ones I get that actually have correct English.

Subject: [Dshield] Odd emails from apparently MS..

I've currently gotten a total of 5 messages this month that contained
various virus/trojans according to Clamav / F-Prot and Sophos that appear to
be from the MS postmaster. IP's and headers match. Has anyone else gotten
any of these? I even went and contacted abuse at microsoft.com about it but
their response was "this appears to be dns spoofing" which I disagree with.
IP spoofs perhaps, or one of their systems could indeed be breeched.
Regardless, the source ip's are now being blocked at my border. Headers from
the latest message are below, all previous messages are exactly the same
source hosts.
