ATTENTION: This IP is infected with, or NATting for a computer infected with a high volume spam sending trojan - it is participating in a botnet.

This is the Cutwail BOT

You need to patch your system and then fix/remove the trojan. Do this before delisting, or you're most likely to be listed again almost immediately.

If this IP is a NAT firewall/gateway, you MUST configure the NAT to prevent outbound port 25 connections to the Internet except from your real mail servers.
