KALI INI KITA AKAN MEMBUAT MAIL SERVER DENGAN UBUNTU 9.10
apache2 , mysql , postfix, dovecot , squirellmail senjata utamanya 
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
| 1 |  root@kaitokid:~# mysql -u root -p // -p masukkan passwd mysql nya | 
| 1 |  <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> | 
| 1 2 |  // ganti 'postfixpasswd' sesuai pasword yang di inginkan & 'postfix'   sesuai dengan user yang dinginkan | 
5. Download postfixadmin untuk mempermudah administrasi mail
| 1 | <em> http://sourceforge.net/projects/postfixadmin/</em> | 
6. Extract hasil download postfixadmin dan pindahkan ke /var/www
| 1 | <em> root@kaitokid:~# cd /var/www/ root@kaitokid:/var/www# tar xzf /home/kaitokid/postfixadmin-2.**.tar.gz root@kaitokid:/var/www# mv postfixadmin-2.**/ postfix root@kaitokid:/var/www# chown -R www-data.www-data /var/www</em> | 
7. Setup config.inc.php postfixadmin
root@kaitokid:~# nano /var/www/postfix/config.inc.php
| 1 2 3 4 5 6 7 8 9 |  // 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
// waktu instalasi pastikan tidak ada error & untuk ppostfixadmin series 2.3 file setup tidak perlu dihapus
//pastikan web server di komputer udah jalan
9. Konfigurasi MySQL postfix
//konfigurasi user & passwd sesuai dg nomer 4
| 1 2 3 4 5 6 7 8 | nano /etc/postfix/mysql_virtual_alias_maps.cf   user = postfix   password = postfixpassword   hosts = 127.0.0.1  dbname = postfix   table = alias   select_field = goto  where_field = address | 
| 1 2 3 4 5 6 7 8 9 | nano /etc/postfix/mysql_virtual_mailbox_maps.cf   user = postfix   password = postfixpassword   hosts = 127.0.0.1  dbname = postfix   table = mailbox   select_field = maildir   where_field = username  #additional_conditions = and active = '1' | 
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | nano /etc/postfix/mysql_virtual_mailbox_limit_maps.cf   user = postfix   password = postfixpassword   hosts = 127.0.0.1  dbname = postfix   table = mailbox   select_field = quota   where_field = username  #additional_conditions = and active = '1' nano /etc/postfix/mysql_virtual_domains_maps.cf   user = postfix   password = postfixpassword   hosts = 127.0.0.1  dbname = postfix   table = domain   select_field = domain   where_field = domain  #additional_conditions = and backupmx = '0' and active = '1' nano /etc/postfix/mysql_relay_domains_maps.cf   user = postfix   password = postfixpassword   hosts = 127.0.0.1  dbname = postfix   table = domain   select_field = domain   where_field = domain  #additional_conditions = and backupmx = '1' | 
| 1 2 3 4 |  chgrp postfix /etc/postfix/mysql_*.cf   chmod 640 /etc/postfix/mysql_*.cf   groupadd -g 5000 vmail   useradd -m -g vmail -u 5000 -d /home/vmail -s /bin/bash vmail | 

10. konfigurasi postfix main.cf
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 |  nano /etc/postfix/main.cf  # Virtual Mailbox Domain Settings  //konfigurasi default main.cf untuk opreknya tunggu di part 2 mail server   myhostname = ubuntu //sesuaikan dg hostname komputer yang dipakai mail server   virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf   virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf   virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf   virtual_mailbox_limit = 51200000  virtual_uid_maps = static:5000  virtual_gid_maps = static:5000  virtual_mailbox_base = /home/vmail   virtual_transport = virtual  # Additional for quota support   virtual_create_maildirsize = yes   virtual_mailbox_extended = yes   virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_mailbox_limit_maps.cf   virtual_mailbox_limit_override = yes   virtual_maildir_limit_message = Sorry, the your maildir has overdrawn your diskspace   quota, please free up some of spaces of your mailbox try again.  virtual_overquota_bounce = yes   alias_maps = hash:/etc/aliases   alias_database = hash:/etc/aliases   mydestination =  relayhost =  mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128  mailbox_size_limit = 0  recipient_delimiter = +  inet_interfaces = all | 
11. Konfigurasi Dovecot POP3 dan IMAP4
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | nano /etc/dovecot/dovecot.conf   protocols = imap pop3   disable_plaintext_auth = no   default_mail_env = maildir:/home/vmail/%u/  first_valid_uid = 5000  first_valid_gid = 5000  # SQL database  passdb sql {  # Path for SQL configuration file   args = /etc/dovecot/dovecot-sql.conf  }  # SQL database  userdb sql {  # Path for SQL configuration file   args = /etc/dovecot/dovecot-sql.conf  } | 
| 1 2 3 4 5 6 | nano /etc/dovecot/dovecot-sql.conf   driver = mysql   connect = host=127.0.0.1 dbname=postfix user=postfix password=postfixpassword   default_pass_scheme = CRYPT   user_query = SELECT maildir, 5000 AS uid, 5000 AS gid FROM mailbox WHERE username = '%u'  password_query = SELECT password FROM mailbox WHERE username = '%u' |
