configuring pop3
 

I am running redhat 9 and using samba as a domain controller
I have a domain from myserver.org because of dynamic ip
so i configured send mail and it works great now for pop3 i have no idea how to configure . the domain my users use is a local domain gnecomputing.cert when i telnet system.gnecomputing.com 110 it says pop3 is running but under gnecomputing.cert i need to tell pop3 to set inbox mail up for say dan@system.gnecomputing.com

is there a add on program for setting up users someone please help because.

from what i read on the internet is that just have the service run and it will have mail boxes for each user and their login password will be the same for e-mail
