If you don't have the attention span to do that, go to spamcop, at http://spamcop.net
Once you verify your e-mail address, you are given an URL you can go to and submit your spam to a script that parses the headers and message for IPs, URLs and E-Mails, then checks them in the abuse.net database for a complaint e-mail address, to which it dispatches an e-mail.
I find it works well. I ran it alongside several of my own searches, and it turned up complaint e-mail addresses far quicker than I can.
