A port open!

I scanned all the ports of my host and i discovered that the port 110 (POP3)is open.

No process uses this port (netstat -pantu).

How to close this port now?

Using yast-firewall i can see that the pop port is close but not in practice.

I want your help guys.

Well, just so we can see, can you output your nmap and netstat commands? Also where did you scan from/to. If you did it over the internet to you PC on a cable modem then it could be something because of your ISP and not you. Or did you do this on an internat network or localhost? Are you sure it said open and not filtered?

I scanned in the same net segment.
I used a win32 program SuperScan.
Netstat seems that no port 110 is open.
