+## 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.
 
-By default, `bridge` runs in non-interactive mode. You must set up the bridge initially.
