Anyone trying to infect me?

I just received a mail that was sent from another customer at my ISP. All my personal virus triggers went off by looking at the layout, headers and attachment filename, but my - otherwise very good - virusscanner didn't notice anything out of the ordinary. I've submitted the sample to Sophos for testing and analyzing. Here's the mail - with stripped headers - as I received it.

SoSmall, SoCold, SoNice, SoGood, SoWarm..

Attachment :

Could this be the next installment of the SoBig series? The "SoSmall, SoCold, SoNice, SoGood, SoWarm.." line could be a pointer, who knows? Anyway, what really confuses me is that neither my scanner, nor the RAV solution that my ISP uses has detected anything strange. It passed all these checks without triggering anything - so it's either brand new and so far unknown virus, or a false alert.

Looking at the headers - and I'm not an expert at all - it tells me the thing has mailed itself from a broadband user to me, avoiding the ISP SMTP server to send itself. This leads me to believe that whatever lurks in has it's own SMTP engine...

I hope for the latter, but on the other hand, I'd be exited to know I helped stop a new epidemic.
