But if there really are some sending legitimate mail, I would be interested in collaborating to maintain a whitelist of them. Need to be LARGE though, to be worthwhile. > dnsbl.njabl.org is a subset of xbl.spamhaus.org According to spamhaus website, they only use the open proxy subset from njabl: 127.0.0.9. When I query njabl, I consider: 127.0.0.2 -- open relays 127.0.0.4 -- spam Sources 127.0.0.8 -- insecure formmail.cgi 127.0.0.9 -- open proxy servers And since I query njabl first, I may as well use the open proxy information from the original source, instead of spamhaus second hand copy.
