First - make SURE to REPORT HIM to the ISP the SPAM-mail came from!

If you use Microsoft Outlook and get email from him ...
In Outlook - Click VIEW Options
This will show you information about what servers the message went through to get to you!
I know it kind of look like geek greek to you, but be patient - Here's a sample of the spam I got last night!

So, looking at all that "stuff", it appears that the mail came from
[email protected]

Now, most ISPS have dealt with SPAM Abusers before, and they often have a special email address like "[email protected]" (if the SPAM came from jnpcs)

Another way to get an email address for that ISP is to try and browse their website.

For the example here where the SPAM came from "[email protected]" - I'd just type www.jnpnw.com into my browser and see what was there. On that site, I finally found a "contact US" page that had an email address I could FORWARD the SPAM to with my thoughts.
