# ProtonMailBridge plus PostFix

## Security:
* GPG stores in-container are set up in a wildly insecure way.
* Compose creates a volume for /root with these stores to preserve bridge cache.
* Therefore, entire setup is extremely insecure.
* All because GPG unlock handling in bridge is still broken upstream as of 2024.

## Setup

Note docker-compose.yaml contains a debian image. This is only for testing inter-container mailing/networking.

Build only seems to require  `#usermod -aG docker username`. Not tested as root/sudo.

By default, `bridge` runs in non-interactive mode on container startup. You must set up the bridge initially:

    cp .env.example .env
    vi .env
    docker-compose build
    docker-compose up -d
    docker-compose exec pmb bash
    killall bridge
    ./bridge -c

When in bridge cli mode:

* `login` will activate account.
* `info` will show creds to input into host filesystem .env postfix values.


    exit
    docker-compose down
    vi .env
    docker-compose up -d

Note: docker-compose down && docker-compose up are necessary. "restart" will not reload .env
