I have searched and played around for a few days and am stuck. I have 2 ISPConfig 3rc2 servers setup. One is my webserver and the other is my dns/mail server. DNS works fine as does my webserver. I cannot figure out how to get the mail server setup. I am using Ubuntu 8.04 LTS for the DNS/Email server and Debian 5.0 for the webserver. I am currently hosting 6 domains. Any help to assist me in properly setting up the mail server will be greatly appreciated.
