Docker-mailserver is a simple, effective mail server for Docker that uses a few scripts and Docker. In this tutorial, we will install the docker-mailserver on FreeBSD latest version.
Before beginning the installation, ensure that you have a working installation of Docker:
pkg install docker
We need to install the necessary packages that are required for the installation of docker-mailserver:
pkg install -y bash ca_root_nss certbot curl git sudo
Clone the docker-mailserver repository using the following command:
git clone https://github.com/docker-mailserver/docker-mailserver.git
Change to the docker-mailserver directory:
cd docker-mailserver
Next, create a copy of env-example as .env and edit the .env file.
cp env-example .env
nano .env
Update the files mail.example.com.crt and mail.example.com.key with your domain certificate and private key location.
After updating the .env file, create a copy of mail.example.com.example as mail.example.com:
cp mail/example.com/example mail/example.com
nano mail/example.com/postmaster@example.com.env
And update mail.example.com/postmaster@example.com.env file as per your requirement.
Now we are ready to build the container:
docker-compose up --build -d
This command will build the container and start it as a daemon. Your mail server is now running.
In this tutorial, we have learned how to install docker-mailserver on FreeBSD latest version. Docker-mailserver is a simple yet effective mail server that is easy to install and configure. You can now start using your mail server and access it from anywhere in the world.
