Spam saga update: The crap they’re selling

After about 21 hours of receiving bounces and failure notices as a result of spammers sending spam claiming to come from andrewraff.com, I have received 307 of these messages.
All of the bounced spam messages link to the web page d23.a1x.net/~admin12/… However, email uses a different prefix before the hostname, such as d23.a1x.net or d23.a1x.net. All contain a 5 digit “psid” variable at the end, such as “psid=17972” or “psid=33794.” This web page advertises “Complete Webmaster Solution,” a set of 25 web page templates, a purported “$2,425 value” and “AdBlaster Pro” software.
The web page is “@2002 NetBiz Inc. All Rights Reserved.” I’m not sure what they mean by “@2002.” Perhaps they mean ©2002? Ironically, even if I wanted to buy this crap, I couldn’t, since I “am not authorized” to view their “Secure Order Form.”
I’m concerned about this not just because of the hundreds of bounced emails I have received in the last day, but because of the possible damage done because of the spammer’s theft of my domain name. If over 300 of these messages bounced back to me, how many of them went through to valid email addresses? How can I recover the value of the damage done to my name by this spammer? (Since this domain is eponymous, my personal reputation is connected to this domain.)
