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?
