# coins-mail-daemon

On start `coins-mail-daemon` fetches all unsent messages from the `mrsdba.mrs_mail` table and queues timeouts internally to send each email based on the records `send_date`. Additionally `coins-mail-daemon` also uses Postgres notify events on the `dd` channel to listen for new records inserted into the `mrs_mail` table.

## .env [Environment Variables]

Coins-Mail-Daemon loads configuration via [dotenv](https://www.npmjs.com/package/dotenv)

- For local development copy `.env.example` to `.env` and edit it's values appropriately
- In deployment however these values are set on the host as [Environment Variables](https://en.wikipedia.org/wiki/Environment_variable) via Ansible deploys

## Recipient Override

Emails created from a non-production server are sent to an admin email account instead of the specified recipient.

- `COINS_ENV=PRODUCTION`
  - emails are sent to the intended recipient like normal
- Any other `COINS_ENV` (for example: `COINS_ENV=development`)
  - email's `sendTo` field will be overwritten with the `ADMIN_EMAIL` value
