Are you sure this is the *full* header, and not a brief view or normal 
view? About all I could say from the above is that vmadmin.com has IP 
216.64.206.101, and that the named dotted decimal IP addresses do not 
have that value. Most of these virii lie about who sent it anyway, so 
iworks at vmadmin.com is probably just another email address the virus was 
aware of, and it used that in the reply-to field. The named addresses 
with dotted decimal format to the side of them seem to be valid, but 
those are just part of the route. pcscom.com is 64.77.28.139, which is 
closest to smtp2.netservers.net, but that doesn't mean much (FYI, 
chuck at pcscom.com is also registered as the admin contact for domain 
pcscom.com, you could probably email a full header to him and ask for 
help figuring it out, but this does not look like a full header...how 
did you obtain this header?).
