Port 110 not connecting

[System]
RedHat 9.0
XMail 1.20 (Newest Version)

[Problems]
-Unable to connect to port 110 from outside the server

[Details]
I am able to telnet to port 110 from inside the server, but from outside the server port 110 timesout and i am unable to connect. I do not have a firewall on port 110.

[Questions]
1) Could there be a software conflict? Are there any programs installed on port 110 by default with RH9 that i dont know about?
2) Is this an XMail configuration problem?

No - only one program can listen on a port at any one time. Any subsequent attempts to listen on the same port will fail.

Run
Code:
lsof -n -i:110

on your machine to show what process is listening on port 110.

Possible, but unlikely. Since you can connect locally but not remotely, I suspect that either the POP3 server is not listening for remote connections (unlikely, as this kind of defeats the point of a POP3 server), or some kind of firewalling is going on that you're not aware of. Post the IP address of this machine, and I can verify whether or not this is the case.

Ahh, i did not know what was running on my own machine. the program "iptables" was running and it had port 110 blocked, so i could only access port 110 from inside the machine. Now everything is working like a charm :-D. For all of you out there that think you dont have a firewall, you may have one that is hidden from you !!
