How to Install MailyGo on macOS

MailyGo is an open-source webmail client that you can install on your own server. You can use it to manage your email accounts and send and receive emails. In this tutorial, we will guide you through the process of installing MailyGo on your macOS computer.

Prerequisites

A macOS computer with admin rights.
Homebrew package manager installed on your computer. If you don't have it already, you can install it by following the instructions on brew.sh.
Git installed on your computer. If you don't have it already, you can install it by running brew install git in your terminal.

Installation

Open your terminal and navigate to the directory where you want to install MailyGo.
```
cd /path/to/your/directory
```

Clone the MailyGo repository from GitHub using Git.

git clone https://github.com/jlelse/MailyGo.git

Change into the newly created MailyGo directory.
```
cd MailyGo
```
Use Homebrew to install the dependencies for building and running MailyGo.
```
brew install go postgresql certbot
```
The go package provides the Go programming language dependencies that MailyGo needs. postgresql sets up a PostgreSQL server on your machine for storing data, and certbot is used to generate and manage SSL certificates for MailyGo.
Set up the PostgreSQL database.
```
createdb mailygo
```
This command creates a new database named mailygo.
Run the build process for MailyGo.
```
go build
```
This command compiles the source code and creates an executable binary file named MailyGo.
Generate an SSL certificate for MailyGo.
```
sudo certbot certonly --standalone -d yourdomain.com
```
Replace "yourdomain.com" with the domain name you'll be using for MailyGo. Follow the instructions and input the necessary information to generate the SSL certificate. Make sure to also set up automatic renewal of the certificate.
Start the MailyGo server.
```
sudo ./MailyGo -env production -db-name mailygo -db-user yourusername -db-password yourpassword -db-sslmode disable -public-address yourdomain.com -tls-cert /etc/letsencrypt/live/yourdomain.com/fullchain.pem -tls-key /etc/letsencrypt/live/yourdomain.com/privkey.pem
```
Replace yourusername, yourpassword, and yourdomain.com with appropriate values. The db-name and db-sslmode flags should be left as-is. The tls-cert and tls-key flags should be set to the full path of your SSL certificate and the private key respectively. The public-address is the fully-qualified domain name of your MailyGo server.
Open your web browser and visit https://yourdomain.com:8080 to access the MailyGo web interface. Use the default login credentials admin and changeme to get started.

Congratulations! You have successfully installed MailyGo on your macOS computer. Enjoy using your own private webmail client.
