Well, but in that case Exchange will add it's own hostname, won't it? So, the problem remains the same. Or doesn't Exchange add a Received line when it gets the mail from the client?
After re-reading http://www.slipstick.com/emo/2003/up031211.htm where it states:

I think I might see some logic at play, although I'm not sure I agree. I suppose Microsoft's logic is that by removing insertion of that header from the client to the server, the decision of what to add can be controlled centrally. In the anti-spam wars, perhaps this makes a twisted kind of sense, in that "normal" users SHOULD be going through a relay server (ISP or corporate).
Still, it's trivial for a spammer to get around this. It would be nice if this were one of their policy settings rather than a blanket default.
