[Ilohamail-users] pop/imap external server

[moncho <mon...@ya...>]

Hi, I'm new to the list, I install a centos 5, I want to use webmail as iloha. 

On a computer I have installed dovecot (pop / imap) and other equipment have sendmail. 
Iloha supports server external pop and smtp? and how to configure this?
I certainly appreciate your responses
