dear Bill....thanks for your replies.....
well, i used this link
Ubuntu 8.04 LTS Server (Hardy Heron) Install Guide - Zimbra :: Wiki
for my setup....the only thing is that i use vmware server to run my ubuntu servers AND i have already set up a web server running....(in it,i have bind installed)
my mail server runs as an indipentent v-machine....do i have to install bind there also?
i'm so confused....
this is the third day i spend to run my mail.......and still searching....
forgive my ignorance please....i'm still learning! so please be more specific if possible....
