# Email Delivery (SendGrid + cPanel)

This app sends email through the notification outbox. The API drains the outbox and delivers via SendGrid Web API.

## Environment

Set these in `.env` (API server):

```
EMAIL_PROVIDER=sendgrid
SENDGRID_API_KEY=your-sendgrid-api-key
EMAIL_FROM="BookYoga <info@bookyoga.in>"
WEB_BASE_URL=https://bookyoga.in
```

## SendGrid setup

1. Create an API key with Mail Send permissions.
2. Verify the sender or authenticate your domain.
3. Test with password reset:

```
curl -X POST http://localhost:3001/api/auth/forgot-password \
  -H "Content-Type: application/json" \
  -d '{"email":"info@bookyoga.in"}'
```

The outbox will drain every minute. You can also drain manually via the admin UI.

## cPanel mailbox (info@bookyoga.in)

Make sure the mailbox exists and email routing is set to Local Mail Exchanger.

DNS records (GoDaddy):

```
Type: A
Host: mail
Points to: <cpanel-server-ip>

Type: MX
Host: @
Points to: mail.bookyoga.in
Priority: 10
```

Verify with:

```
dig mx bookyoga.in
dig a mail.bookyoga.in
```

## Admin tools

- Admin UI: `/dashboard/admin/notifications`
- Drain pending: sends queued items with advisory lock
- Force drain: bypasses the lock if a previous drain is stuck

## Troubleshooting

- `Deferred` with timeout: MX missing or mail server unreachable.
- `550 relay not permitted`: mailbox not local on cPanel or mail routing set to Remote.
- `Dropped` or `Bounced`: check SendGrid Suppressions and remove the address, then retry.
