It appears to be infected with a spam sending trojan, proxy or some other form of botnet. It was last detected at 2014-07-01 02:00 GMT (+/- 30 minutes), approximately 4 days, 7 hours ago. This IP is infected (or NATting for a computer that is infected) with the kelihos spambot. In other words, it's participating in a botnet. If you simply remove the listing without ensuring that the infection is removed (or the NAT secured), it will probably relist again. --- -- syafril ------- Syafril Hermansyah Running MDaemon 14.0.3 Beta B, SP 4.5.0 Beta B Victory has a thousand fathers, but defeat is an orphan. -- John Fitzgerald Kennedy -- --[MDaemon-L]------------------------------------------------ Milis ini untuk Diskusi antar pengguna MDaemon Mail Server.
