Mail. CentOS 5.2. Version 1.0 Author: Falko Timme <ft [at] falkotimme [dot] com> Last edited 06/26/2008 This tutorial shows how to set up a CentOS 5.2 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 5.2, but should apply to the 64-bit version with very little modifications as well. Varnish. Wiki. Nginx.
