This tutorial shows how to set up a CentOS 5.1 based server that offers all services needed by ISPs and web 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. This tutorial is written for the 32-bit version of CentOS 5.1, but should apply to the 64-bit version with very little modifications as well.

I will use the following software:

• Web Server: Apache 2.2 with PHP 5.1.6
• Database Server: MySQL 5.0
• Mail Server: Postfix
• DNS Server: BIND9 (chrooted)
• FTP Server: Proftpd
• POP3/IMAP server: Dovecot
• Webalizer for web site statistics

In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig (i.e., ISPConfig runs on it out of the box).

I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!
