Setting up your own mail server can be a daunting task, but it can also be a great learning experience. In this article, we will guide you through the process of configuring a mail server on Ubuntu 12.04.
Introduction
Before we dive into the technicalities of mail server configuration, let’s first understand what a mail server is and what it does. A mail server is a software application that handles incoming and outgoing mail traffic. It is responsible for storing, sending, and receiving email messages. Setting up your own mail server can help you achieve greater control over your email communications and improve security.
However, setting up a mail server can be challenging, especially if you are new to the process. Ubuntu 12.04 is an older version of the popular Linux-based operating system, but it is still widely used by individuals and organizations. We will discuss the step-by-step process of configuring a mail server on Ubuntu 12.04, so you can set up your own mail server with confidence.

Step-by-Step Guide to Mail Server Configuration in Ubuntu 12.04
Step 1: Update Ubuntu 12.04
The first step is to ensure that your Ubuntu 12.04 system is up-to-date. You can do this by running the following command:
sudo apt-get update && sudo apt-get upgrade
This command will update the package lists, and upgrade any outdated packages on your system.
Step 2: Install the Mail Server Packages
The next step is to install the mail server packages. We will be using Postfix as our mail transfer agent, Dovecot as our mail delivery agent, and Roundcube as our webmail interface. You can install these packages by running the following command:
sudo apt-get install postfix dovecot-core dovecot-imapd dovecot-lmtpd roundcube roundcube-plugins
This will install all the necessary packages for our mail server configuration.
Step 3: Configure Postfix
The next step is to configure Postfix. Postfix is a mail transfer agent that routes email messages from one server to another. You can configure Postfix by editing the main configuration file /etc/postfix/main.cf using your favorite text editor. Here’s an example configuration:
...myhostname = mail.example.commydomain = example.commyorigin = $mydomainmynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128inet_interfaces = allsmtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)smtp_tls_security_level = maysmtpd_tls_security_level = may...
You can customize the configuration file according to your needs. After editing the configuration file, restart the Postfix service:
sudo service postfix restart
Step 4: Configure Dovecot
The next step is to configure Dovecot. Dovecot is a mail delivery agent that stores email messages on the server and allows users to access their email via IMAP or POP3 protocols. You can configure Dovecot by editing the main configuration file /etc/dovecot/dovecot.conf using your favorite text editor. Here’s an example configuration:
...protocols = imap lmtplisten = *disable_plaintext_auth = nossl = yesssl_cert = ssl_key = mail_location = maildir:/var/mail/vhosts/%d/%nuserdb {driver = passwd}passdb {driver = passwd}...
Again, you can customize the configuration file according to your needs. After editing the configuration file, restart the Dovecot service:
sudo service dovecot restart
Step 5: Configure Roundcube
The next step is to configure Roundcube. Roundcube is a webmail interface that allows users to access their email via a web browser. You can configure Roundcube by editing the main configuration file /etc/roundcube/config.inc.php using your favorite text editor. Here’s an example configuration:
...$config['default_host'] = 'ssl://mail.example.com';$config['smtp_server'] = 'ssl://mail.example.com';...
You can customize the configuration file according to your needs. After editing the configuration file, restart the Apache service:
sudo service apache2 restart
Step 6: Configure DNS
The next step is to configure DNS for your domain name. You will need to create the necessary DNS records to point your domain’s MX record to your mail server’s public IP address. You can do this through your domain registrar’s control panel.
Step 7: Create Mail Users
The final step is to create mail users. You can create mail users using the following command:
sudo useradd -m -s /usr/sbin/nologin username
Replace username with the name of the user you want to create. You can then set the user’s password using the passwd command.
