Howtoforge posted a guide about setting up Mandriva 2009.1 as server

This tutorial shows how to set up a Mandriva 2009.1 Free (x86_64) server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig 2 (i.e., ISPConfig runs on it out of the box). This tutorial is written for the 64-bit version of Mandriva 2009.1.
