Default Iptables Help

Hello,

I have configured a routeing server using iptables for the localnetwork. I often get error messages when i connect to our mail server especially pop3 . When i checked the mail server log it said

"Maximum connection limit reached for ip="My routing server ip"
So i increased the no of pop3 connections to the mail server. But that doen't solve the problem. I suspect that one or more of the local network network machines is compramised and that is causing the problems.

Now, i want to log the pop3 connections that are sent out from my localnetwork to my mail server using IPTABLES so that i can get an idea which machine is causing this. I tried a no of rules and i am lost...

Can anyone please help me to write that iptables rule..

Thanks in advance..

Santhosh.
