SpamCannibal Zone File

Contains IP addresses and ranges that have sent spam, virus payloads, or warning bounce messages concerning known spam/virus mail (addressed back to a bogus envelope sender in our domain) to our mail servers. In general this zone file does not contain IP addresses that are found in other DNSBL's since we strive not to duplicate information available elsewhere. Our border systems that run SpamCannibal daemons use various DNSBL's to reject unwanted spam and virus traffic in addition to the information found in this zone file
