Exploit IP Blocklist

An exploit IP blocklist is a blocklist that contains IP addresses that have been observed to behave in certain ways that a genuine SMTP client never would.

IP addresses found on this list will either be compromised, botnet/virus-infected, proxies, VPNs, TOR exit nodes, or IPs that are NAT’ing for these hosts.
