I no longer use this myself, and unfortunately I have no time available to maintain it.

Fork

This fork modifies some base images to be compatible with raspberry pi.

Instructions for use:

• Run the following commands to download docker-compose file and environment variables

wget -O docker-compose.yml https://raw.githubusercontent.com/MFAshby/Mailu/master/docker-compose.yml.sample wget -O .env https://raw.githubusercontent.com/MFAshby/Mailu/master/.env.sample

• Modify .env for your own requirements
• If using SSL certificates, you should add the relevant cert.pem and key.pem files to /var/lib/mailu/certs/
• Bring up all images with docker-compose up (-d for background mode)

If you prefer to build the images yourself:

• Clone the repository
• Copy docker-compose.yml.sample to docker-compose.yml and uncomment the build: sections
• Copy .env.sample to .env and modify as you require
• Run the following to start

docker-compose build && docker-compose up -d
