Email addresses are irrelevant, unless the spammers are stupid enough to give you a valid reply
address (like "write to sales@idiot.com for a catalog!"). The name of the game in
spam-busting is the
Received: headers.
Track the
spam back to the
SMTP server it was sent from. Do a
WHOIS on that
domain. Email the listed
sysadmin, as well as abuse@that_domain.com and explain how
open relays are just like letting spammers steal their
money. Also:
- If they list a web site, WHOIS again and send more email. If they own the domain, TRACEROUTE and do recursive WHOISes until you find their provider.
- If the URL is a weird 10 to 12 digit decimal number, convert it to 8 digits of hex, break the hex into 4 parts, and convert the parts back to decimal to get the real IP. Then DNSQuery on the IP.
- If they have an 800 number, call them repeatedly and waste their time.
