Postfix Virtual Domain Mail Server
Sekarang akan kita bahas cara membuat virtual domain dengan menggunakan postfix admin, dovecot dan database mysql.
Langkah yang perlu kita tempuh adalah:
1. Download source postfix admin di
http://sourceforge.net/projects/postfixadmin/
2. kemudian extraxt di direktori /var/www/
root@budi-desktop:~# cd /var/www/
root@budi-desktop:/var/www# tar xzf /home/ardelindo/Desktop/postfixadmin-2.2.1.1.tar.gz
root@budi-desktop:/var/www# mv postfixadmin-2.2.1.1/ postfix
root@budi-desktop:/var/www# chown -R www-data.www-data /var/www
3. Install aplikasi utama
root@budi-desktop:~# apt-get install postfix postfix-msql php5-imap dovecot-pop3d dovecot-imapd php5-mysql squirrelmail
4. Buat database postfix
root@budi-desktop:~# mysql
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
5. Setup config.inc.php postfixadmin
root@budi-desktop:~# vim /var/www/postfix/config.inc.php
// Database Config
// mysql = MySQL 3.23 and 4.0
// mysqli = MySQL 4.1
// pgsql = PostgreSQL
$CONF['database_type'] = 'mysql';
$CONF['database_host'] = 'localhost';
$CONF['database_user'] = 'postfix';
$CONF['database_password'] = 'postfixpassword';
$CONF['database_name'] = 'postfix';
$CONF['database_prefix'] = '';
6. Setup postfix admin
buka web browser firefox kemudian buka URL
http://127.0.0.1/postfix/setup.php
setelah selesai hapus setup.php
root@budi-desktop:~# rm -fr /var/www/postfix/setup.php
7. Konfigurasi MySQL postfix
vim /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
vim /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'
vim /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'
vim /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'
vim /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'
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
8. Konfigurasi /etc/postfix/main.cf
vim /etc/postfix/main.cf
# Virtual Mailbox Domain Settings
myhostname = ubuntu
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_minimum_uid = 5000
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
9. Konfigurasi Dovecot POP3 dan IMAP4
vim /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
}
vim /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'
10. Test Dovecot POP3 dan IMAP4
/etc/init.d/dovecot restart
root@budi-desktop:~# telnet 127.0.0.1 110

vim /etc/postfix/main.cf
smtpd_recipient_restrictions = reject_unauth_pipelining, permit_mynetworks,
