Doesn’t mean it doesn’t happen – only that you’re not on any “narrowcast” lists (e.g. “Email 200,000 British business addresses!”) A number of otherwise-legitimate companies will send to those lists. SpamAssassin’s fixed rules will do very little against these spammers – they’re using the same e-mail engines, the same language, and the same sort of Internet connections as other companies with opt-in mailing lists. For some addresses, they represent the vast majority of spam that gets past SpamAssassin. Fortunately, they often do use and re-use the same IP addresses and the same domains, and can be blocked that way. http://groups.google.com/group/news.admin.net-abuse.email/browse_thread/thread/78ac67e56ce35d90 lists a good (bad?) selection of them… James. -- E-mail: james@ | Remember, half-measures can be very effective if all you aprilcottage.co.uk | deal with are half-wits.
