This is a detailed description about how to set up an OpenSUSE 10.3 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. This tutorial is written for the 32-bit version of OpenSUSE 10.3, but should apply to the 64-bit version with very little modifications as well.
