EmailRelay is an open-source Mail Transfer Agent (MTA), which acts as a bridge between different email clients and servers. It can be used to store, forward, and filter emails across different accounts and domains. In this tutorial, we will learn how to install EmailRelay on an EndeavourOS Latest system.

Prerequisites

Before proceeding with the installation process, ensure that you have the following:

  • An EndeavourOS Latest system
  • Sudo access or root privileges
  • Basic knowledge of Linux commands and networking

Step 1: Update the System

It is always recommended to update the package lists and upgrade the installed packages to their latest versions before installing any new software.

To update the system, launch a terminal and run the following command:

sudo pacman -Syu

Step 2: Install EmailRelay

EmailRelay is available in the official Arch Linux repositories. Therefore, you can easily install it using the following command:

sudo pacman -S emailrelay

This command will install the latest version of EmailRelay and all its dependencies.

Step 3: Configure EmailRelay

After installing EmailRelay, you need to configure it to work with your email accounts and domains.

The configuration file of EmailRelay is located at /etc/emailrelay.conf. You can edit this file using your favorite text editor.

Before editing the configuration file, make a copy of the default configuration file as a backup:

sudo cp /etc/emailrelay.conf /etc/emailrelay.conf.orig

To edit the configuration file, run the following command:

sudo nano /etc/emailrelay.conf

In this file, you need to specify the email accounts and domains that EmailRelay should handle.

Here is an example configuration file:

SMTP_SERVER=smtp.yourisp.com
SMTP_PORT=25
SMTP_LOGIN=user:password
ACCEPT=127.0.0.1;192.168.0.0/16
REQUIRE_AUTH=1

The above configuration specifies the following parameters:

  • SMTP_SERVER: The SMTP server that EmailRelay should use to send and receive emails.
  • SMTP_PORT: The port number of the SMTP server.
  • SMTP_LOGIN: The username and password to authenticate to the SMTP server.
  • ACCEPT: The list of IP addresses or network subnets that EmailRelay should accept emails from.
  • REQUIRE_AUTH: Specifies if EmailRelay should require authentication for incoming emails.

Refer to the EmailRelay documentation for more detailed configuration options.

Step 4: Start EmailRelay

After configuring EmailRelay, you can start it using the following command:

sudo systemctl start emailrelay

You can also enable EmailRelay to start automatically at boot time using the following command:

sudo systemctl enable emailrelay

To verify that EmailRelay is running, you can check its status using the following command:

sudo systemctl status emailrelay

This command should output the status of EmailRelay, indicating whether it is running or not.
