ftp

Introduction:

Setting up your own email server on Ubuntu Server allows you to have complete control over your email communication without relying on third-party services. By following these instructions, you can bypass daily email limits and ensure reliable delivery for your business or personal needs.

Setting up your own email server on Ubuntu 22.04 involves several steps including installing and configuring the necessary software, setting up DNS records, and securing your server. Below are the instructions, commands, and DNS records you’ll need:

Step 1: Install Required Packages

sudo apt update && sudo apt upgrade

Set the Server Hostname.

sudo hostnamectl set-hostname mail.yourdomain.com

Install MySQL Server

sudo apt install mysql-server

Now install Postfix, Devcot and Roundcube

sudo apt install postfix dovecot-core dovecot-imapd dovecot-pop3d roundcube roundcube-core roundcube-mysql

During the installation, you will be prompted to configure Postfix. Choose “Internet Site” and enter your domain name when prompted. Setup the Database Password for roundcube as well in this step.

Step 2: Configure Postfix

Edit Postfix Configuration:

sudo nano /etc/postfix/main.cf

Ensure the following settings are configured or adjusted:

myhostname = mail.yourdomain.com
mydomain = yourdomain.com

Restart Postfix

sudo systemctl restart postfix

Step 3: Configure Dovecot

Edit Dovecot Configuration:

sudo nano /etc/dovecot/dovecot.conf

Ensure the following settings are configured or adjusted:

listen = *
mail_location = maildir:~/Maildir

Edit Dovecot Authentication Configuration:

sudo nano /etc/dovecot/conf.d/10-auth.conf

Ensure the following settings are configured or adjusted:

disable_plaintext_auth = no
auth_mechanisms = plain login

Restart Dovecot

sudo systemctl restart dovecot

Step 4: Roundcube Installation and Configuration:

Download Roundcube:

cd /tmp
wget https://github.com/roundcube/roundcubemail/releases/download/1.5.2/roundcubemail-1.5.2-complete.tar.gz

Extract Roundcube:

tar -zxvf roundcubemail-1.5.2-complete.tar.gz
sudo mv roundcubemail-1.5.2 /var/www/html/roundcube

Create Roundcube Configuration File:

sudo cp /var/www/html/roundcube/config/config.inc.php.sample /var/www/html/roundcube/config/config.inc.php

Edit Roundcube Configuration:

sudo nano /var/www/html/roundcube/config/config.inc.php

Change password in the below line:

$config['db_dsnw'] = 'mysql://roundcube:PASSWORD@localhost/roundcube';

Set Permissions:

sudo chown -R www-data:www-data /var/www/html/roundcube

Access Roundcube via Browser:

Open a web browser and go to http://mail.yourdomain.com/roundcube to complete Roundcube setup.

Step 5. DNS Changes:

Here are the DNS records you need to create on your domain registrar’s control panel:

Required Records:

A Record:

Translate domain names (like “yourdomain.com”) to IP addresses (like “111.22.333.44”) for web browsing.

Name: mail.yourdomain.com

Value: 111.22.333.44 (Your server’s IP address)

TTL: You can use the default TTL (usually 3600 seconds or 1 hour)

MX Record:

Direct incoming emails to the specific server that handles them.

Priority: Set a low priority (e.g., 10) initially

Name: @ (or leave blank for the root domain)

Value: mail.yourdomain.com

TTL: You can use the default TTL

SPF Record:

Helps prevent email spoofing by identifying authorized mail servers for your domain.

Name: @ (or leave blank for the root domain)

Value: The generated SPF record string (e.g., “v=spf1 mx:mail.yourdomain.com ~all”).

TTL: You can use the default TTL
