postfix adalah sebuah program pengirim email sebagai pengganti dari sendmail.
Postfix is a free and open-source mail transfer agent (MTA) that routes and delivers electronic mail.
It is intended as a fast, easier-to-administer, and secure alternative to the widely-used Sendmail MTA. (wiki)
Dovecot is an open source IMAP and POP3 server for Linux/UNIX-like systems, written primarily with security in mind. Developed by Timo Sirainen, Dovecot was first released in July 2002. Dovecot primarily aims to be a lightweight, fast and easy to set up open source mailserver. (wiki)
1. Persiapan sistem untuk Ubuntu 9.10
Agar nantinya tidak terdapat broken system alangkah baek nya install ubuntu dengan build essential
sudo apt-get install build-essential
2. Install file utama
sudo apt-get install postfix postfix-msql php5-imap dovecot-pop3d dovecot-imapd
php5-mysql squirrelmail apache2
3. Cek system apakah apache2 postfix dan dovecot ny udah ada lum disystem
service apache2 status && service postfix status && service dovecot status
4. Buat Database Untuk Postfix

<em>mysql> create database postfix; mysql> grant all privileges on postfix.* to 'postfix'@'localhost' identified by 'postfixpassword'; mysql> grant all privileges on postfix.* to 'postfix'@'127.0.0.1' identified by 'postfixpassword'; mysql> exit</em>

// Database Config
// mysql = MySQL 3.23 and 4.0
// mysqli = MySQL 4.1
// pgsql = PostgreSQL
$CONF['database_type'] = 'mysqli'; //sesuaikan dg sql nya untuk mysql seri 4 keatas gunakan mysqli
$CONF['database_host'] = 'localhost';
$CONF['database_user'] = 'postfix'; // user database di mysql lihat nomer 4
$CONF['database_password'] = 'postfixpassword'; // user database mysql lihat nomer 4
$CONF['database_name'] = 'postfix'; $CONF['database_prefix'] = ''; //default kosong
|
8. Setup postfix admin
buka web browser firefox kemudian buka URL
http://127.0.0.1/postfix/setup.php
http://127.0.0.1/postfix/setup.php
// waktu instalasi pastikan tidak ada error & untuk ppostfixadmin series 2.3 file setup tidak perlu dihapus
//pastikan web server di komputer udah jalan
