Tutorial: How to Install Postal on Fedora Server Latest

Postal is an open-source mail delivery platform that allows you to send and receive emails from your own server. In this tutorial, we will guide you through the process of installing Postal on Fedora Server Latest.

Prerequisites

  • A Fedora Server Latest installation
  • A domain name set up with DNS records pointing to your server
  • Root access to the server

Step 1: Update the System

Before we can begin with the installation, it is important to make sure your system is up to date. You can do this by running the following command:

sudo dnf update

Step 2: Install Postal Dependencies and Mail Server

Postal has multiple dependencies which must be installed before installing Postal. Furthermore, Postal requires a mail server installed on the system to function. We recommend using Postfix, which is the default mail server installed on Fedora. To install Postfix and the dependencies needed for Postal, run the following command:

sudo dnf install -y curl gnupg2 jq sqlite3 openssl postfix

Step 3: Install Node.js

Postal is built using Node.js, so we must install Node.js before installing Postal. The latest version of Node.js can be downloaded from the NodeSource repository. Run the following commands to add the NodeSource repository and install Node.js:

curl -sL https://rpm.nodesource.com/setup_14.x | sudo bash -
sudo dnf install -y nodejs

Step 4: Install Postal

Now that we have all the prerequisites installed, we can proceed with installing Postal. Postal can be installed via a one-line command using the following command:

curl -s https://postal.atech.media/setup.sh | sudo bash

This command downloads the Postal setup script and runs it as a root user using sudo.

Step 5: Configure Postal

After installing Postal, we must configure it to be able to use it. Configuration files are stored in the directory /opt/postal/config. Configurations for the Web server, database, and email server can be found in this directory.

To start the Postal service, run the following command:

sudo postal start

You should see output similar to:

Starting Postal. Please wait as this could take a little while...
