Linux Mail Server Setup and Howto Guide

Hi

I have a LAN with 30 users – Server is based on Centos 4.8. Users use Samba Server to log on to the server from their XP based machines. I administer the network using Webmin in terms of adding new users.

It is necessary to set up an INTERNAL e-mail system which will allow them to send mail to designated internal addresses and it is not intended that they should be able to use the Internet.

I intend to follow the Linux Mail Server Setup and How to guide based on Centos 4 to do this. I understand that this uses Postfix and as I understand Dovecot is needed for the Pop3 access.

In terms of my requirements I would be interested to hear any comments  or details of any changes needed.

Regards

Dave
