Im totally new to linux, used to be with windows mail server before this, so i assume i know how things work around in theory.

Currently all my email hosted outside of the office, i have more than 100 email user account created over there, so i plan to build up 1 local mail server to reduce my office network bandwidth.

Not all user will be created in my local mail server because i do not have static ip for my local mail server, maybe around 90, and another 10 will be remain outside so they will able to check mail anywhere, so 90 that created locally will send internal mail easily within the local mail server.

How can i do that? i try ispconfig, postfix, fetchmail in centos but im stuck, any guide for me?

if you want your user access mail from local as well from outside,
use configure sendmail which listen on all interfaces, set relaying and local domain names in files,
configure dovecot , you require static ip address , configure webmail (squirrelmail), configure your firewall to open smtp and pop/imap ports
and using webbrowser you can access webmail from anywhere.
