設置的目的

• Web Server: Apache 2.0.x
• Mail Server: Postfix (easier to configure than sendmail; has a shorter history of security holes than sendmail)
• DNS Server: BIND9
• FTP Server: proftpd
• POP3/POP3s/IMAP/IMAPs: in this example you can choose between the traditional UNIX mailbox format (we then use ipopd/uw-imapd) or the Maildir format (in this case we will use Courier-POP3/Courier-IMAP).
• Webalizer for web site statistics
