Step 1: Install Debian 7

The first step is to install Debian 7 on your system. You can download the Debian 7 ISO from the official website and boot it from a DVD or USB drive. Follow the installation wizard to complete the installation process. Make sure that you select “mail server” during the installation process.

Step 2: Install Postfix Mail Server

Postfix is a popular mail server that is widely used in the Debian community. To install Postfix, open the terminal and enter the following command:

sudo apt-get install postfix

The installation process will take a few minutes to complete. Once it is finished, you will be prompted to configure Postfix. Choose “Internet Site” as the configuration type and enter the fully qualified domain name (FQDN) of your server when prompted.

Step 3: Install and Configure Dovecot

Dovecot is a powerful and secure IMAP and POP3 server that integrates seamlessly with Postfix. To install Dovecot, enter the following command:

sudo apt-get install dovecot-imapd dovecot-pop3d

Once the installation is complete, you will need to configure Dovecot to work with Postfix. Open the file “/etc/dovecot/dovecot.conf” and make the following changes:

protocols = imap pop3

mail_location = maildir:/var/mail/vhosts/%d/%n

auth_username_format = %n

Restart Dovecot using the following command:

sudo service dovecot restart

Step 4: Install and Configure Roundcube

Roundcube is a free and open-source webmail client that allows users to access their email accounts from a web browser. To install Roundcube, enter the following command:

sudo apt-get install roundcube roundcube-plugins roundcube-plugins-extra

You will be prompted to configure Roundcube during the installation process. Enter the FQDN of your server when prompted, and choose “Yes” when asked to configure the database.

Open the file “/etc/apache2/conf.d/roundcube.conf” and make the following changes:

RewriteEngine On

RewriteRule ^$ /roundcube/ [R]

RewriteRule ^roundcube/$ /roundcube/index.php

Restart Apache using the following command:

sudo service apache2 restart

Step 5: Configure DNS Settings

In order for your mail server to work properly, you will need to configure your DNS settings. This involves creating an MX record that points to your server’s IP address. Consult your domain registrar’s documentation for instructions on how to do this.

Step 6: Configure Firewall Settings

Finally, you will need to configure your firewall settings to allow traffic to and from your mail server. Open the terminal and enter the following commands:

sudo iptables -A INPUT -p tcp --dport 25 -j ACCEPT

sudo iptables -A INPUT -p tcp --dport 143 -j ACCEPT

sudo iptables -A INPUT -p tcp --dport 993 -j ACCEPT
