Install and Configure PostfixAdmin
It is needed to install httpd,mysql and php for PostfixAdmin.
# yum install mysql-server php php-mysql php-imap php-mbstring -y
Once all the above packages were installed, make sure httpd and mysqld services are running.
It is needed to create db, db user for PostfixAdmin. Here i am using the following db details. Change the following details as you prefered.
DB: postfix
DB User: postfix
Password: postfix
The following command will create the DB for postfix. You can also execute these queries directly in the mysql console.
# mysql -e "CREATE DATABASE postfix;"
# mysql -e "CREATE USER postfix@localhost IDENTIFIED BY 'postfix';"
# mysql -e "GRANT ALL PRIVILEGES ON postfix.* TO postfix;"
To download and fix permissions of PostfixAdmin.
# yum install -y subversion
# cd /usr/local/
The following command will download latest PostfixAdmin package. The 'svn' command is available in the package 'subversion' which we have already installed.
# svn co http://svn.code.sf.net/p/postfixadmin/code/trunk postfixadmin
# chmod 777 /usr/local/postfixadmin/templates_c
Edit the postfixadmin configuration file, /usr/local/postfixadmin/config.inc.php and update the following lines as shown below.
$CONF['configured'] = true;
$CONF['postfix_admin_url'] = '/postfixadmin';
$CONF['database_type'] = 'mysqli';
$CONF['database_host'] = 'localhost';
$CONF['database_user'] = 'postfix';
$CONF['database_password'] = 'postfix';
$CONF['database_name'] = 'postfix';
$CONF['domain_path'] = 'YES';
$CONF['domain_in_mailbox'] = 'NO';
$CONF['encrypt'] = 'cleartext';
$CONF['emailcheck_resolve_domain] = 'NO';
Once you have done the above changes, you have to create the following entry in httpd.conf to access postfixadmin via browser.
Alias /postfixadmin /usr/local/postfixadmin
Restart httpd service
# /etc/init.d/httpd restart
Now you can access postfixadmin using the following url. Setup the postfixadmin as per the given instructon in there.
http://<IP>/postfixadmin/setup.php
Once the setup is completed successsfully, it is time to install and configure postfix service.
Install and Configure Postfix
There will be a postfix package initiallly in the default installation. Here i am removing it and i am using Postfix-2.9.7. Depending upon the version and architecture, select the postfix version from http://packages.oostergo.net/
To download and install postfix
# rpm -Uvh http://packages.oostergo.net/postfix-2.9/el6/postfix-2.9.7-1.el6.x86_64.rpm
The following commands will made the changes in /etc/postfix/main.cf. We have to setup it initially.
To set postfix's hostname.
# postconf -e "myhostname = mail.sudosu.in"
# postconf -e "mydomain = sudosu.in"
# postconf -e "myorigin = "'$'"mydomain"
inet_interfaces initially set for listening from localhost only. We need to change it to listen on all interfaces.
# postconf -e "inet_interfaces = all"
# postconf -e "inet_protocols = ipv4"
# postconf -e "home_mailbox = Maildir/"
# postconf -e "smtpd_banner = "'$'"myhostname ESMTP"
To limit an email size 10M
# postconf -e "message_size_limit = 10485760"
To limit mailbox 1G
# postconf -e "mailbox_size_limit = 1073741824"
# postconf -e "mydestination = "'$'"myhostname, localhost."'$'"mydomain, localhost"
Create a user 'vmail' for creating virtual users(mail boxes)
# groupadd -g 5000 vmail
# useradd -g vmail -u 5000 vmail -d /home/vmail -m
It is needed to create some configuration files to map the domains and mailboxs from mysql. Here are those configuration files.
# cat /etc/postfix/mysql-domains.cf
hosts = localhost
user = postfix
password = postfix
dbname = postfix
table = domain
select_field = domain
where_field = domain
additional_conditions = and backupmx = '0' and active = '1'
# cat /etc/postfix/mysql-users.cf
hosts = localhost
user = postfix
password = postfix
dbname = postfix
table = mailbox
select_field = maildir
where_field = username
additional_conditions = and active = '1'
result_format = %sMaildir/
# cat /etc/postfix/mysql-aliases.cf
hosts = localhost
user = postfix
password = postfix
dbname = postfix
table = alias
select_field = goto
where_field = address
additional_conditions = and active = '1'
The above configuration files and 'vmail' user need to map with postfix.
# postconf -e "virtual_mailbox_domains = mysql:/etc/postfix/mysql-domains.cf"
# postconf -e "virtual_mailbox_maps = mysql:/etc/postfix/mysql-users.cf"
# postconf -e "virtual_alias_maps = mysql:/etc/postfix/mysql-aliases.cf"
# postconf -e "virtual_mailbox_base = /home/vmail"
# postconf -e "virtual_uid_maps = static:5000"
# postconf -e "virtual_gid_maps = static:5000"
Restart or reload postfix
# postfix reload
or
# /etc/init.d/postfix restart
Install and Configure Dovecot
# yum install dovecot dovecot-mysql -y
Check if postfix support dovecot authentication. Check if dovecot is listed in the result.
# postconf -a
cyrus
dovecot
Postfix configuration for Dovecot SMTP-Auth settings
# postconf -e "smtpd_sasl_local_domain = $myhostname"
# postconf -e "smtpd_sasl_auth_enable = yes"
# postconf -e "broken_sasl_auth_clients = yes"
# postconf -e "smtpd_sasl_type = dovecot"
# postconf -e "smtpd_sasl_path = private/auth"
# postconf -e "smtpd_sasl_security_options = noanonymous"
# postconf -e "smtpd_sender_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, permit"
# postconf -e "smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination"
Create dovecot-mysql.conf file as follows.
[root@server ~]# cat /etc/dovecot/dovecot-mysql.conf
driver = mysql
connect = host=localhost dbname=postfix user=postfix password=postfix
default_pass_scheme = PLAIN
password_query = SELECT password FROM mailbox WHERE username = '%u' AND active = '1'
Create dovecot.conf file as follows.
[root@server ~]# cat /etc/dovecot/dovecot.conf
auth_debug = yes
auth_mechanisms = plain login
auth_username_format = %Lu
auth_verbose = yes
mbox_write_locks = fcntl
passdb {
driver = pam
}
passdb {
driver = pam
}
passdb {
args = /etc/dovecot/dovecot-mysql.conf
driver = sql
}
service auth {
unix_listener /var/spool/postfix/private/auth {
group = postfix
mode = 0660
user = postfix
}
user = root
}
ssl_cert = </etc/pki/dovecot/certs/dovecot.pem
ssl_key = </etc/pki/dovecot/private/dovecot.pem
userdb {
driver = passwd
}
userdb {
driver = passwd
}
userdb {
args = uid=5000 gid=5000 home=/home/vmail/%d/%n
driver = static
}
Once the above settings has been completed, restart postfix and dovecot and verify the installation using telnet.
# /etc/init.d/dovecot restart
# /etc/init.d/postfix restart
Install and Configure RoundCubeMail
Download RoundCubeMail code
You can install latest roudcube using git.
# yum install git -y
# cd /usr/local
# git clone git://github.com/roundcube/roundcubemail.git
You can find a directory named 'roundcubemail' after the above step.
Install Necessary Packages
Install the following packages for the working if roundcube.
# yum install httpd php php-common php-json php-xml php-mbstring php-imap php-pear php-mysql mysql mysql-server
You have to add the following entries in the httpd.conf to access roundcube via browser.
Alias /roundcube /usr/local/roundcubemail
Restart httpd service.
# /etc/init.d/httpd restart
Necessary DataBase setup
Here i am using the following details for the DB setup. You can change it as you like.
DB: roundcubemail
DB User: roundcubemail
Password: roundcube_pass
# mysql -e "CREATE DATABASE roundcubemail;"
# mysql -e "GRANT ALL PRIVILEGES ON roundcubemail.* TO roundcube@localhost IDENTIFIED BY 'roundcube_pass';"
# mysql roundcubemail < /usr/local/roundcubemail/SQL/mysql.initial.sql
You can now access roundcube using the following url. You have to follow the instruction to complete the installation.
http://<IP>/roundcube/installer/
Once the installation completed, http://<IP>/roundcube allow you to login to the mail accounts.
