but not all that much spam. A lot of spam spoofs headers or hijacks isp's as relays, and is tough to trace. There are also mail senders that bypass isp's altogether and are tougher to trace. Replyto's and such can be easily spoofed.
Anyway, here's a quick tutorial on how to interpret email headers:
http://support.earthlink.net/support/TUTORIALS/email/mbx_interpret_headers.jspNote the number 68.184.242.183 that seems to be from charter-stl.com. That could be the originating IP address.
Plug that number into the search box at:
http://www.iks-jena.de/cgi-bin/whois (don't worry-- the important stuff is in English)
And you get Charter Communications in St. Louis, and a complaint address of abuse@charter.net
If you are going to make a complaint to them, make sure that ALL the headers are in the email you forward to them.
on edit:
Doh! Spoke too soon.
Charter got it from-- 68.27.195.244 which is a Sprint IP. Somebody else may know enough to tell if this is a dedicated IP for this guy.
