If you're the postmaster at your domain, use postfix and setup some decent header/body filters to reject the mail with an appropriate smtp-response to the sending host. Postfix is also able to pass such <> bounces (just tested it locally). Furthermore, you're able to filter hosts which do not have a valid hostname in their HELO/EHLO command, which is often not setup correctly by spammers. This is IMHO the only way to let the spammers know that they are unwanted. Although, if I look at my logs, some of them are just ridiculously persistent... Oh, and every once in a while I get caught by the debian-list. I wrote to the listmaster twice or more already, never got an answer. If I had too many bounces, I got kicked off the list. I could understand this, if the number of rejects is high enough. But, because the listserver is doing only one delivery attempt, I feel, the number (which I haven't figured out, yet...) is currently too low. In one case I was kicked off the list, even though there was no recent bounce in my logs, just accepted mails. :-( This, I didn't understand. One more nuisance: if spam hits debian-user and I get trapped by that listserver-soft, I get kicked off any debian-* list! If I would get kicked off the list I bounced, ok, understandable, but _all_ lists?? Anybody else around here to answer those questions? -- Tschoe, http://gecius.de/gpg-key.txt - Fingerprint: Jens 1AAB 67A2 1068 77CA 6B0A 41A4 18D4 A89B 28D0 F097 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
