Mailpit using docker-compose

This project sets up a Mailpit container (mailpit) for handling email testing and development.

Prerequisites

• Docker installed and running (https://docs.docker.com/engine/install/)
• Docker Compose installed and running (https://docs.docker.com/compose/install/)

Environment Variables

This docker-compose.yml file utilizes environment variables to customize configurations. You can set these variables before running commands:

• MP_MAX_MESSAGES: Maximum number of messages to retain (defaults to 5000)
• MP_DATABASE: Path to the Mailpit database (defaults to /data/mailpit.db)
• MP_SMTP_AUTH_ACCEPT_ANY: Accept any SMTP authentication (defaults to 1)
• MP_SMTP_AUTH_ALLOW_INSECURE: Allow insecure SMTP authentication (defaults to 1)
• WEB_PORT: Port to expose the Mailpit web interface (defaults to 8025)
• SMTP_PORT: Port to expose the Mailpit SMTP interface (defaults to 1025)

Recommendation: Customize these environment variables in the docker-compose.yml file or use a .env file to set them as per your requirements.

Usage

1. Create a .env file (optional):

   • Create a file named .env in the same directory as your docker-compose.yml file.

   • Add environment variable definitions in the format KEY=VALUE, one per line. For example:

     MP_MAX_MESSAGES=5000
     MP_DATABASE=/data/mailpit.db
     MP_SMTP_AUTH_ACCEPT_ANY=1
     MP_SMTP_AUTH_ALLOW_INSECURE=1
     

2. Start the services:

   docker-compose up -d

   • This will create and start the Mailpit container in detached mode (background).

3. Access Mailpit:

   • Open your web browser and navigate to http://localhost:<WEB_PORT>, replacing <WEB_PORT> with the port you configured (default: 8025).
