The Mailspike Blacklist
The mailspike services help identify and block known spammers. These services are intended to provide all receivers and reputation providers a baseline of data to help block the senders with the worst reputations. All listed IP addresses are being continually monitored and the lists are updated frequently.
This blacklist combines both the z.mailspike.net and IP addresses from rep.mailspike.net that are listed between L3 and L5. This combined zone can be used for a single DNS query to determine if messages coming from this IP address should be blocked. The DNS A record is always mapped either to 127.0.0.2 (z.mailspike.net) or the corresponding A record from rep.mailspike.net.
