This tutorial will guide you through the process of installing Mailcow on NixOS Latest, which is a Linux distribution based on the Nix package manager. Mailcow is a self-hosted mail server solution that includes various services such as SMTP, IMAP, POP3, and webmail.
Before we begin, make sure you have the following prerequisites:
First, we need to update and upgrade the system packages to ensure that we have the latest packages installed. To do this, run the following command:
sudo nix-channel --update
sudo nixos-rebuild switch --upgrade
Next, we need to install the required packages to install and run Mailcow. Run the following command to install the required packages:
sudo nix-env -iA nixos.curl nixos.gnupg nixos.docker
Now, we will clone the Mailcow repository using Git. Run the following command to clone the repository:
sudo git clone https://github.com/mailcow/mailcow-dockerized.git /opt/mailcow/
Next, we will configure Mailcow. Navigate to the Mailcow directory using the following command:
cd /opt/mailcow/
First, we need to generate passwords for the Mailcow installation using the provided command in the Mailcow directory:
sudo ./generate_config.sh
Next, we need to configure the Mailcow settings. Run the following command to edit the Mailcow configuration file:
sudo nano mailcow.conf
Edit the following settings in the configuration file:
# Mailcow settings
MAILCOW_HOSTNAME="your_domain.com"
SYSLOG_MAIL="logfile"
# MySQL settings
DBNAME="mailcow"
DBUSER="mailcow"
DBPASS="database_password"
DBROOT="root_password"
# Mailcow credentials
ACME_EMAIL="admin@your_domain.com"
MAILCOW_EMAIL="admin@your_domain.com"
MAILCOW_PASSWORD="mailcow_password"
Make sure to replace the values with your own.
Next, we need to configure Docker-compose by running the following command:
sudo nano docker-compose.yml
Edit the following settings in the configuration file:
version: '2'
services:
#...
nginx-mailcow:
#...
hostname: mailcow
domainname: your_domain.com
mysql-mailcow:
#...
environment:
MYSQL_ROOT_PASSWORD: root_password
MYSQL_DATABASE: mailcow
MYSQL_USER: mailcow
MYSQL_PASSWORD: database_password
#...
Replace the values with your own.
Next, we will deploy Mailcow using Docker-compose. Run the following command to deploy Mailcow:
sudo mailcow up -d
Wait for the deployment to complete.
Finally, we can access Mailcow by navigating to the Mailcow web interface. Open a web browser and navigate to:
https://your_domain.com
You should see the Mailcow web interface login page. Login using the credentials you set in the configuration file.
Congratulations! You have successfully installed Mailcow on NixOS Latest.
