This tutorial shows how to prepare a Debian 8 (Jessie) server (with nginx, BIND, Dovecot) for the installation of ISPConfig, and how to install ISPConfig 3.1. ISPConfig 3 is a web hosting control panel that allows you to configure the following services through a web browser: Apache or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers nginx (instead of Apache), BIND as DNS server, and Dovecot (instead of Courier).
