I have setup a linux red hat 8 server with sendmail and POP3. I want to host my own mail server
I can send/receive email across the internet.
I cannot get my windows 2000 workstation using outlook to get mail using pop3 from the linux box.
It is iptables that is doing it because when i stop iptables i can get through. When i start my iptables it fails on getting a response from my POP3 server and logging onto POP3 server.
Here is my iptables - Can someone help me out please?
chain input policy accept
RH-Lokkit-0-50-INPUT all anywhere anywhere
Accept tcp anywhere anywhere tcp dpt:http
Accept tcp anywhere anywhere tcp dpt:smtp

Can someone help me out please? My linux box is not directly attached to the router. It is sitting on the lan. I use internal interface as eth0 and external is ppp0 (i think). How can i find this out for sure?
