Prerequisites

Before we begin, you'll need the following:

  • A Debian Latest server instance
  • A non-root user with sudo privileges
  • A domain name
  • 2 DNS records pointing to your server IP (A record and MX record)

Step 1: Update your System

Before installing any package, it's a good practice to update your system to the latest version. This can be done by running;

sudo apt update
sudo apt upgrade

Step 2: Install Required Dependencies

Next, we'll need to install several dependencies. Enter the following command to install them:

sudo apt install -y golang-go git gcc build-essential

Step 3: Install Excision Mail

After installing the necessary dependencies, we can proceed with the installation of Excision Mail by running:

go get -u github.com/Excision-Mail/Excision-Mail

This command will download and install the source code of Excision Mail from GitHub. It will also compile the code into an executable binary file.

Step 4: Configure Excision Mail

Before starting the Excision Mail server, we'll need to configure the following environment variables by creating a .env file in the Excision-Mail directory.

cd $HOME/go/src/github.com/Excision-Mail/Excision-Mail
touch .env
nano .env

Add the following content to the .env file:

HOST=my-exc email.example.com
PORT=587
[email protected]
PASSWORD=your_password
SMTP_SERVER=Your_SMTP_server_address
SMTP_PORT=Your_SMTP_server_port

Step 5: Start Excision Mail

After configuring Excision Mail, we can now start the server by running:

Step 6: Verify the Installation

To verify that Excision Mail is running correctly, open your web browser and go to https://your_domain.com:2020.

This will take you to the Excision Mail login page, where you can use the username and password you set in Step 4 to log in and access the Excision Mail dashboard.

Step 7: Connect Your Email Client

Now that you have successfully installed Excision Mail, you can connect your email client to the server.

Here are manual configuration settings you should use:

  • Incoming mail server - IMAP: mail.your-domain.com, Port: 993
  • Incoming mail server - POP: mail.your-domain.com, Port: 995
  • Outgoing mail server - SMTP: mail.your-domain.com, Port: 587
