As a related issue, how do people feel about a

servers, It looks like it's not good to just whitelist NZ IPs
Since I've got a little time now I'll clarify this since there seems
to be a little bit of Interest.
Depending on what mailing list software people use it's possible to
whitelist, blacklist or give positive or negative scores (eg in
Spamassassin) to groups of Networks and IPs.
On a per country basis you might wish to give a positive (more likely to
send spam) to Chinese networks and a negative (less likely to send spam)
to New Zealand IPs. You can you the zones "cn.rbl.cluecentral.net" and
"nz..rbl.cluecentral.net" for this or other lists.
However as has become obvious in the last week some NZ IPs are a lot more
likely to send Spam than others. I'm therefore thinking about setting up a
listing of IPs (available as a list and/or as a DNSBL/DNSBLs) that would
further break down NZ IPs space. This would aid people in filtering and
specifically in Whitelisting "trusted" Servers.
I'm thinking of the following Classes of Networks/IPs:
1. Trusted Servers (ie Trademe, Qantas) serving controlled populations
2. Servers Handling traffic from untrusted customers (ie most IP's
3. Dynamic IPs allocated by ISPs to customers.
4. Very untrustworthy IPs allocated by ISPs to Cyber Cafes and the like.
If possible I'd like the IPs owners (users/whatever) to contribute the
data but I'd  probably accept data from elsewhere if the range's owner
didn't send it to me.
How do people feel about the idea? Specifically:
a. Do you think it's a good idea? If not why not?
b. Would you use it?
c. Do you think you would contributed your IPs to it?
d. Are you interested in helping run the list?
Replies to me and I'll summarize to the list might be best.
 This sort of implies I'm running it but that might not be the case.
