I tend to be pretty good at reading mail headers, so
if you'd like to follow up by sending the headers to

Alternatively, you might try SPAM-L. Subscribe,
and post your question with a prefix of "HELP:" e.g.
Subject: HELP: Please help me track the origin of this message
http://www.claws-and-paws.com/spam-l/ has the FAQ,
with lots of good info including how to subscribe.
