2. Spam sent using spamware - programs specifically designed to send huge amounts of email (up to 100,000 emails an hour) over an ordinary dialup internet connection.
This software is designed to steal service from an innocent third party by relaying email through their server.
It's also designed to forge the email headers to deflect complaints away from the perpetrator, either towards the third-party or towards yet another innocent bystander. The load this puts on the third-party server can bring an ISP down for days.
3. 'Professional' spamhauses. These are
company’s setup purely to commit theft and fraud. They have permanent internet connections, or sometimes have their servers in the premises of other crooked service providers.
They don't usually spam to advertise themselves, instead they find clueless businessmen and charge them $1000 or so to send their advert to hundreds of thousands of people's mailboxes.

bounced, blacklist and delete spam emails from your ISPs mail server without
having to download it into your email client. |
Hunt the perpetrators down. Complain to their upstream provider. Repeatedly
get them shut down. Get the servers, web pages and email addresses of the advertisers yanked. Invoice them for your time
or sue them in a small claims court when they don't pay up. Report the illegal schemes to the local police.
Tracing the perpetrators using spamware, or the spamhauses requires some familiarity with email headers--see bottom of page on
