How to Install Maddy Mail Server on NetBSD

Maddy is a simple and fast mail server for Linux/BSD systems. In this tutorial, we will demonstrate how to install Maddy Mail Server on NetBSD.

Prerequisites

Before proceeding further, ensure that your NetBSD system is up-to-date and has the following requirements:

• NetBSD version 9.0 or higher
• Root access
• GCC package installed
• Git package installed

Install Go

Maddy is a Go language program. Therefore, to install Maddy, you will need to install the Go compiler on your system.

Step 1: Download Go Binary

First, download the latest Go Binary package from the official website:

$ wget https://golang.org/dl/go1.16.linux-amd64.tar.gz

Step 2: Extract Go Binary

After downloading the Go Binary package, extract it to the /usr/local directory by running the following command:

$ sudo tar -xvf go1.16.linux-amd64.tar.gz -C /usr/local

Step 3: Set Go Environment Variables

After extracting the package, you need to set up some environment variables for Go to function correctly. To set up the variables, open the /root/.profile file with a text editor:

$ vi /root/.profile

Add the following lines to the bottom of the file:

export PATH=$PATH:/usr/local/go/bin
export GO_PATH=${HOME}/go
export GO_BIN=${GO_PATH}/bin

Save and close the file, then run the following command to apply the changes:

$ source /root/.profile

Install Maddy

Now that you have installed Go, you can proceed with the installation of Maddy:

Step 1: Clone Maddy Repository

To start the installation, you will first need to clone the Maddy Git repository:

$ git clone https://github.com/foxcpp/maddy.git
$ cd maddy

Step 2: Build Maddy

After cloning the repository, use the go build command to build Maddy:

$ go build -o maddy ./cmd/maddy

This will create a binary called maddy in the current directory.

Step 3: Install Maddy

To install Maddy, copy the maddy binary to the /usr/local/bin directory:

$ sudo cp maddy /usr/local/bin

Step 4: Configure and Run Maddy

Now you can configure Maddy for your requirements. Create a configuration file called maddy.conf in the /usr/local/etc/maddy directory:

$ sudo mkdir /usr/local/etc/maddy
$ sudo vi /usr/local/etc/maddy/maddy.conf

Here is an example configuration file for Maddy:

log_to_journal = true

#[log]
#level = "debug"
#to = "file:/var/log/maddy.log"

[http]
listen = "localhost:3000"

[smtp]
listen = "0.0.0.0:25"
auth {
  anonymous_allowed = true
}
forward {
  domains = ["example.com"]
  to = ["example@gmail.com"]
  tls_policy = "optional"
}

[submission]
listen = "0.0.0.0:587"
auth {
  methods = ["plain"]
  file = "/usr/local/etc/maddy/users"
}

[pop3]
listen = "0.0.0.0:110"
auth {
  methods = ["plain"]
  file = "/usr/local/etc/maddy/users"
}

Save and close the file.

After configuring the server, you can start it by running the following command:

$ sudo maddy -config /usr/local/etc/maddy/maddy.conf

That's it! You have successfully installed and configured Maddy on NetBSD. You can now test and use the mail server.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
