Important Terminologies

Before we delve into the configuration process, let’s have a quick rundown of some important terminologies in mail server configuration:

• Mail Transfer Agent (MTA) – Software responsible for routing emails between servers.
• Domain Name System (DNS) – Translates domain names into IP addresses.
• Mail Delivery Agent (MDA) – Software responsible for saving incoming emails to the user’s mailbox.
• Post Office Protocol (POP) – Protocol used for downloading emails from the server to the user’s device.
• Internet Message Access Protocol (IMAP) – Protocol used for accessing emails stored on the server.

Prerequisites for Configuring Mail Server using Apache

Before proceeding with the configuration process, make sure you have the following:

• A server with a clean installation of Apache and the necessary packages installed.
• A registered domain name that will act as your server’s hostname.
• A basic understanding of Linux commands and file editing.
• An SSL/TLS certificate for secure email transmission (optional but highly recommended).

Configuring Mail Server using Apache: Step-by-Step Guide

Now, let’s dive into the actual configuration process:

1. Install Required Packages

The first step is to install the necessary packages needed for the mail server to operate. Run the following command on the terminal:

sudo apt-get install postfix dovecot postfix-mysql dovecot-mysql mysql-server

2. Configure Postfix

Postfix is the MTA used by Apache mail server. To configure Postfix, follow these steps:

Step 1:

Edit the Postfix configuration file:

sudo nano /etc/postfix/main.cf

Step 2:

Define the server’s hostname and domain name:

myhostname = mail.example.com
mydomain = example.com

Step 3:

Set the transport protocol to SMTPS:

smtpd_use_tls=yes
smtp_use_tls=yes
smtp_tls_security_level = may
smtpd_tls_security_level = may
smtp_tls_CApath = /etc/ssl/certs
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

Step 4:

Set the email relay settings:

relay_domains = $mydestination
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination

Step 5:

Save the changes and exit the editor.

3. Configure Dovecot

Dovecot is the MDA used by Apache mail server. To configure Dovecot, follow these steps:

Step 1:

Edit the Dovecot configuration file:

sudo nano /etc/dovecot/dovecot.conf

Step 2:

Define the server’s hostname and domain name:

hostname = mail.example.com
auth_mechanisms = plain login

Step 3:

Set the SSL/TLS settings for secure email transmission:

ssl = required
ssl_cert = /etc/ssl/certs/example.com.crt
ssl_key = /etc/ssl/private/example.com.key

Step 4:

Set the mailbox location:

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

Step 5:

Save the changes and exit the editor.

4. Create Database and User for Mail Server

You need to create a database and user that will hold user email accounts. To create a database and user, follow these steps:

Step 1:

Log in to your MySQL server:

sudo mysql

Step 2:

Create a new database:

CREATE DATABASE mailserver;

Step 3:

Create a new user:

CREATE USER 'mailuser'@'localhost' IDENTIFIED BY 'password';

Step 4:

Grant the user access to the database:

GRANT ALL PRIVILEGES ON mailserver.* TO 'mailuser'@'localhost';

Step 5:

Save the changes and exit MySQL.

5. Add User Accounts

Now that the mail server is configured, you need to add user accounts. To add a user account, follow these steps:

Step 1:

Create a new user:

sudo useradd -r -u 150 -g mail -d /var/mail virtual_user

Step 2:

Create a new directory for the user’s mailbox:

sudo mkdir -p /var/mail/virtual/example.com/user

Step 3:

Set proper permissions for the directory:

sudo chown -R virtual_user:mail /var/mail/virtual/example.com/user
sudo chmod -R 770 /var/mail/virtual/example.com/user

Step 4:

Create a new email account:

sudo doveadm pw -s SHA512-CRYPT

Step 5:

Enter a password for the email account when prompted:

Enter new password:
Retype new password:
{SHA512-CRYPT}$6$SALT$PASSWORDHASH

Step 6:

Add the email account to the database:

sudo mysql
USE mailserver;
INSERT INTO users (email, password) VALUES ('user@example.com', '{SHA512-CRYPT}$6$SALT$PASSWORDHASH');

6. Configure Email Client

After setting up the mail server, you can now configure your email client to access your email account. To configure your email client, follow these steps:

Step 1:

Open your email client and navigate to the account settings.

Step 2:

Enter your email address and password.

Step 3:

Select IMAP or POP as the incoming mail protocol.

Step 4:

Enter the server hostname and port number.

Step 5:

Select SSL/TLS as the encryption method.

Step 6:

Save the changes and test your email client by sending and receiving emails.
