Cara Membuat Mail Server + Virtual Domain di Ubuntu

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

root@kaitokid:~# mysql -u root -p     // -p masukkan passwd mysql nya

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

// ganti 'postfixpasswd' sesuai pasword yang di inginkan & 'postfix'
     sesuai dengan user yang dinginkan

5. Download postfixadmin untuk mempermudah administrasi mail

 http://sourceforge.net/projects/postfixadmin/

6. Extract hasil download postfixadmin dan pindahkan ke /var/www

 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

7. Setup config.inc.php postfixadmin

root@kaitokid:~# nano /var/www/postfix/config.inc.php

// 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

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

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'

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'

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

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

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
   }

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'

ok sampai disini dulu happy mailing and happy ubuntu
