Gray Duck Mail is a self-hosted email solution that runs on your own server. In this tutorial, we will guide you through the process of installing Gray Duck Mail on NetBSD.

Prerequisites

Before we begin, you will need the following:

A server running NetBSD
A domain name configured with DNS pointing to your server

Step 1: Install Dependencies

To run Gray Duck Mail, we need to install some dependencies. Run the following commands to install them:

# pkg_add ruby26 ruby26-json ruby26-libyaml postgresql13-server postfix

Step 2: Configure the PostgreSQL Server

Gray Duck Mail uses PostgreSQL as its database, so we need to configure it before proceeding. Follow these steps to set up PostgreSQL:

Initialize the database cluster:

# su - _postgresql
$ initdb -D /var/postgresql/data

Start the PostgreSQL server:
```

```

Set a password for the postgres user:

$ createuser --superuser postgres

Next, we need to configure Gray Duck Mail. Copy the example configuration file and edit it:

# cp config/config.yml.example config/config.yml
# vi config/config.yml

In this file, you will need to enter your domain name and PostgreSQL database configuration.

Step 5: Initialize the Database

Now that we have configured Gray Duck Mail, we can initialize the database with the following command:

# bin/gray_duck_db create

Step 6: Start Gray Duck Mail

Finally, we are ready to start Gray Duck Mail with the following command:
