How to Install LibreMailer on Fedora CoreOS Latest

LibreMailer is an open-source email management software. If you are looking to install LibreMailer on Fedora CoreOS Latest, we have got you covered. This tutorial will guide you through the installation process.

Prerequisites

Before we begin, make sure you have the following:

• SSH access to your Fedora CoreOS Latest instance
• A user account with sudo access

Step 1 - Update your System

You should always update your system to the latest version to ensure that you are installing the software without any conflicts. To update your Fedora CoreOS Latest instance, run the following command:

sudo dnf update -y

Step 2 - Install Required Dependencies

LibreMailer requires a few dependencies to be installed on your system. Run the following command to download and install necessary dependencies:

sudo dnf install -y git make gcc golang pam-devel

Step 3 - Clone the LibreMailer Repository

To install LibreMailer, we will first need to clone the repository. Run the following command to clone the repository:

git clone https://github.com/averna-syd/LibreMailer.git

Step 4 - Build and Install LibreMailer

Now that we have cloned the LibreMailer repository, we can build and install it on our system. Navigate to the LibreMailer directory where you have the cloned repository, and run the following command to build the LibreMailer:

make

Once the build is complete, run the following command to install the LibreMailer:

sudo make install

Step 5 - Configure LibreMailer

At this point, we have successfully installed the LibreMailer on our Fedora CoreOS Latest instance. However, we need to configure it to work correctly. First, we need to configure the librepam_unix.so module to allow logging in with the email address instead of the username. Run the following command to edit the system-auth file:

sudo vi /etc/pam.d/system-auth

Modify the following line:

auth        sufficient   pam_unix.so nullok try_first_pass

To:

auth        sufficient   pam_unix.so nullok try_first_pass likeauth=nullop use_first_pass

Now save and exit from the file.

Next, we need to create a new configuration file for LibreMailer, run the following command to create a new configuration file:

sudo vi /etc/libremailer/libremailer.conf

Now add the following lines to the libremailer.conf file to configure LibreMailer:

## Mail server ##
smtp_hostname = smtp.example.com
smtp_port = 587
smtp_username = your-smtp-username
smtp_password = your-smtp-password
smtp_tls = true

## Mailboxes and aliases ##
mail_db = /usr/share/libremailer/mail.db
alias_db = /usr/share/libremailer/aliases
group_db = /usr/share/libremailer/groups
mailbox_path = /var/spool/mail
default_home_dir = /home
default_shell = /bin/bash
use_useradd = true

Make sure to replace the configuration with your own email server details.

Finally, create a new system service file for the LibreMailer using the following command:

sudo vi /etc/systemd/system/libremailer.service

Add the following lines to the libremailer.service file:

[Unit]
Description=LibreMailer Service
After=network.target

[Service]
Restart=always
User=libremailer
ExecStart=/usr/bin/libremailer -config /etc/libremailer/libremailer.conf
WorkingDirectory=/var/lib/libremailer

[Install]
WantedBy=multi-user.target

Save and exit from the file.

Step 6 - Start and Enable the Service

Now that we have configured everything, we can start and enable the LibreMailer Service using the following command:

sudo systemctl enable --now libremailer.service

Congratulation, you have successfully installed LibreMailer on your Fedora CoreOS Latest instance. You can now use it to manage your emails.
