Mailhog

Mailhog is an SMTP server used for testing various applications that send emails. It provides a simple web interface to view what messages have been sent. Let’s edit our new ~/Desktop/op/docker/docker-compose.yml file and add the following to configure Mailhog.

version: "3"
services:

  mailhog:
    image: mailhog/mailhog
    container_name: mailhog
    environment:
      - VIRTUAL_HOST=mailhog.docker
    logging:
      driver: 'none'  # disable saving logs

Now we should be able to bring up our docker compose environment to test that it is working.

cd ~/Desktop/op/docker/
sudo docker compose up

Let’s open up the web interface now http://mailhog.docker:8025/.
