I don't know, but I checked my firewall settings, the same settings was on the system, I have not done any adjustments on it, from the time I install the mail system. When I made an nmap from another server, it showed that port 25 is open.

Code:
Starting Nmap 4.62 ( http://nmap.org ) at 2010-07-27 13:26 PHT
Interesting ports on 121.97.76.4.BTI.NET.PH (121.97.76.4):
Not shown: 1707 closed ports
PORT    STATE SERVICE
22/tcp  open  ssh
25/tcp  open  smtp
53/tcp  open  domain
80/tcp  open  http
110/tcp open  pop3
143/tcp open  imap
993/tcp open  imaps
995/tcp open  pop3s
...
On the URLs, yes, I can actually connect to them. But my concern is that why is it that my server seems to send so many emails to different addresses in just a matter of seconds. Is there a freeware tool to check if the system has indeed some sort of a malware?
