Depends on how easy you find it to type a command, or use a website.  View the
headers for the email, follow the Recieved: header lines, the ones closer to the
top are the ones closer to you.  The one you're more interested in, is the first
Recieved: header, which *should* give you an IP address that connected to the
mail server to send the mail.  Then use a resource such as http://samspade.org
and in the "Do Stuff" box, put that IP address in.  Samspade then runs numerous
queries, and *should* be able to tell you which network the user connected from,
and contact details for that block of IP addresses.  That is basically all
spamcop does, just saves you a fair bit of work :)

Lets take for an example, the email I'm replying to... The last received line
shows this:

Received: from [198.92.66.52] by omclust1.macnet.com (NTMail
7.02.3037/NT2917.00.86700c28) with ESMTP id qaypggaa for
[EMAIL PROTECTED]; Sun, 23 Jun 2002 10:21:44 -0700

Now if we break it down... 198.92.66.52 is the IP address of the computer that
connected to the mail server, omclust1.macnet.com is the mail server, running NT
mail service.  Samspade.org then returns that that IP address is being run on a
service called Online-Mac... the contact for that domain is
[EMAIL PROTECTED] took me all of 5 mins, but takes spamcop 30 seconds to
do it all for me ;)

Hope this gives you a hint as in how the system works.
