Here are examples of the Received Headers for the type of spam that are being sent with forged email addresses for a domain that I host. These at the last 10 bounced messages that I received, so it is fairly representative.
Granted, 3 out of 10 messages originated in Romania. However, 3 out of 10 messages originated in the US. I am looking at the first (bottom) Received Header in each case. I send complaints to the abuse email address listed in the WHOIS record for this IP Address. Do you think that these are victims of some sort that their ISP would want to help? Jim BTW, Notice that the HELO signatures have an identifying characteristic: ljxr.pzt mclbfk.wdui zsgnwd.zctjrq tmoju.zxlvfn sq.ywima sejah.nehj btm.ssp ggav monmib yo.iszxuj - They look ramdomized to me.
