Voici un tutoriel d’installation pour le groupe Postfix, Dovecot et roundcube
Sommaire
Installer un serveur de messagerie sur ubuntu 14.04 ( POSTFIX – DOVECOT -ROUNDCUBE)
Requis:
- Serveur : Ubuntu 14.04 LTS
Ce tutoriel explique commant creer un serveur de mail sous ubuntu 14.04
Voici les paquets que nous allons utiliser
Etape 1 – Installer le server de mail
Installer l’hôte dans /etc/hosts192.168.0.1 mail.bsymedia.com
Installer et configurer postfix
sudo apt-get install postfix
sudo dpkg-reconfigure postfix
Maintenant vous pourrez afficher ces détails. Choisissez vos informations et remplacer bsymedia.com par votre nom de domaine.
1. Internet Site
2. bsymedia.com
3. postmaster@bsymedia.com
4. bsymedia.com, second-domain.com, localhost.localdomain, localhost
5. No
6. 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
7. 0
8. +
9. all
Step 3
Configure postfix for SMTP-AUTH using Dovecot SASL by adding the below lines to postfix config file /etc/postfix/main.cf
.
home_mailbox = Maildir/
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_local_domain =
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_sasl_auth_enable = yes
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination
smtp_tls_security_level = may
smtpd_tls_security_level = may
smtp_tls_note_starttls_offer = yes
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
Step 4
Now generate a digital certificate for tls. Issue the commands one by one and provide details as per your domain.
openssl genrsa -des3 -out server.key 2048
openssl rsa -in server.key -out server.key.insecure
mv server.key server.key.secure
mv server.key.insecure server.key
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
sudo cp server.crt /etc/ssl/certs
sudo cp server.key /etc/ssl/private
Step 5
Now configure certificate path :
sudo postconf -e 'smtpd_tls_key_file = /etc/ssl/private/server.key'
sudo postconf -e 'smtpd_tls_cert_file = /etc/ssl/certs/server.crt'
Step 6
Now enable submission for smtp access through 587. Open /etc/postfix/master.cf file and uncomment below lines.
submission inet n - - - - smtpd
-o syslog_name=postfix/submission
-o smtpd_tls_security_level=encrypt
-o smtpd_sasl_auth_enable=yes
-o smtpd_relay_restrictions=permit_sasl_authenticated,reject
-o milter_macro_daemon_name=ORIGINATING
Step 7
Now install Dovecot SASL by typing the below command. sudo apt-get install dovecot-common
Step 8
Make changes to the files as follows.
Open /etc/dovecot/conf.d/10-master.conf file and find # Postfix smtp-auth line ( line no:95 ) and add the below lines .
# Postfix smtp-auth
unix_listener /var/spool/postfix/private/auth {
mode = 0660
user = postfix
group = postfix
}
Open /etc/dovecot/conf.d/10-auth.conf file and find (line no:100) auth_mechanisms = plain
and replace auth_mechanisms = plain login
Step 9
Restart postfix and dovecot services
sudo service postfix restart
sudo service dovecot restart
INSTALLING AND CONFIGURING DOVECOT
Step 1
Install dovecot using the below command :sudo apt-get install dovecot-imapd dovecot-pop3d
Step 2
Now configure mailbox. Open /etc/dovecot/conf.d/10-mail.conf file and find (Line no:30 ) mail_location = mbox:~/mail:INBOX=/var/mail/%u
Replace with mail_location = maildir:~/Maildir
Step 3
Now change pop3uidlformat . Open /etc/dovecot/conf.d/20-pop3.conf file and find and uncomment the below line ( Line no : 50 )pop3_uidl_format = %08Xu%08Xv
Step 4
Now enable SSL . Open /etc/dovecot/conf.d/10-ssl.conf file and find and uncomment the below line ( Line no : 6 )ssl = yes
Step 5
Restart dovecot service.sudo service dovecot restart
INSTALLING AND CONFIGURING ROUNDCUBE WEBMAIL
Step 1
Download RoundCube from following Link :
RoundCube Download Page
Unzip and copy the whole folder to document_root
of http server.
Make sure that the following directories (and the files within) are writable by the web server user:
- temp
- logs
Step 2 Database Configuration
Next thing we need to do is decide what database backend we’ll use. The most common is MySQL but others are PostgreSQL and SQLite. So once you decide, create a database with any name you want and grant privileges to a separate database user. It’s recommended not to use an existing user or root.
With MySQL you can set up the database by issuing the following commands:
CREATE DATABASE roundcubemail;
GRANT ALL PRIVILEGES ON roundcubemail.* TO username@localhost IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
(of course you have to replace the database, username and password accordingly)
Step 3 Configuring RoundCube
After uploading the files point your browser to http://url-to-roundcube/installer/ to start the install wizard.
In case you see some red NOT OK messages, you need to install or enable something. Follow the links or find out more by searching your web site for your server’s operating system or http://www.php.net.
If the mail server supports SSL
connection for imap and TLS
for SMTP, then SMTPServer will be tls://localhost
and IMAPServer will be ssl://localhost
.
Step 4 Protect your installation
Access through your webserver to at least the following directories should be denied:
- /config
- /temp
- /logs
Roundcube use .htaccess files to protect this directories, be sure to allow override of the Limit directives to get them taken into account.
Last but not least you have to remove the whole installer directory from the webserver. If this remains active it can expose the configuration including passwords.
ETC
Add user account
sudo useradd -m username -s /sbin/nologin
sudo passwd username
Mail forwarding
- Using aliases file
vi /etc/aliases
master: root, user00, root@bsymedia.com
newaliases
- Making
.forward
file in user home directory
vi $HOME/.forward
user00@forward.mail.com
