`POSTGRES_MIN_POOL_SIZE`	Minimum connections in the PostgreSQL pool.	No
`POSTGRES_MAX_POOL_SIZE`	Maximum connections in the PostgreSQL pool.	No

Set these variables appropriately either as environment variables in your shell, in a .env file, or directly pass them when running the Docker container.

Running the Middleware

Run the following command to start the middleware container, replacing <value> placeholders with your specific configuration:

docker run -e MAIL_SERVER_URI=<value> \
           -e MAIL_SERVER_API_KEY=<value> \
           -e POSTGRES_URL=<value> \
           git.spgrn.com/seang96/stalwart-simplelogin-middleware-web:latest
