How to Install docker-mailserver on Manjaro

docker-mailserver is a popular open-source mail server that can be run on Docker. In this tutorial, we will guide you through the installation process of docker-mailserver on Manjaro OS.

Prerequisites

Manjaro OS installed
Docker installed
Basic knowledge of Linux command line

Installation Steps

Ensure that Docker is installed on your Manjaro OS. If you have not installed Docker before, you can follow the official installation documentation.
Open your terminal and run the following command to download the docker-mailserver image:
```
docker pull tvial/docker-mailserver:latest
```
This command will download the latest version of docker-mailserver image to your Manjaro OS.
Next, navigate to where you want to store your mailserver configuration files. In this example, we will use the directory /home/user/mailserver.
```
mkdir /home/user/mailserver
cd /home/user/mailserver
```
Once you have created the mailserver directory, you can run the following command to generate the initial configuration files:
```
docker run --rm \
    -e maildomain=mydomain.com \
    -e [email protected]:user_password \
    -e smtp_port=587 \
    -e imap_port=144 \
    tvial/docker-mailserver:latest generate-configuration > mailserver.env
```
This will create the mailserver.env file containing the initial configuration. Replace the maildomain, smtp_user, and smtp_port with your mail domain, SMTP username, and SMTP port.
Edit the mailserver.env file to customize the settings to your needs:
```
nano mailserver.env
```
You can make changes such as adding aliases, virtual users, and SPF records. Save your changes.
Finally, to start your docker-mailserver, run the following command:
```
docker run --detach --restart always --name mailserver \
    --env-file mailserver.env \
    -p "25:25" -p "587:587" -p "143:143" -p "144:144" \
    -v maildata:/var/mail \
    -v mailstate:/var/mail-state \
    tvial/docker-mailserver:latest
```
This command will start the Docker container with the name mailserver. It will use the mailserver.env file to configure the mail server settings. It will also expose the necessary ports for SMTP and IMAP. The -v flag is used to mount two data volumes maildata and mailstate.

That’s it! Your docker-mailserver is now up and running on Manjaro OS. You can test your mail server by sending and receiving emails.
