I got thousands of emails from some idiot promoting his site. No response from his host, and no response from his upstream provier (except the standard autoreply).
2 weeks later, I did get a message from his host saying he's been null routed. Presumably because I set up my email client (
www.pocomail.com) to filter for the address and send the full header plus my letter of complaint to the host (all addresses shown on their site - including sales) and and the upstream provider.
I sent them over 600 emails (one-4-one for each one I got and kept saying "for your convenience, I include a copy of the email as sent to me"... Fully automated, of course, so I was not inconvenienced.
I also told them I was logging each email and preparing a report to
http://www.mail-abuse.org
Anyway - it worked. This guy was doing it all from the USA. If it had been from Romania or somewhere, it probably woulda failed...
