## How It Works

```
User requests password reset
         ↓
Controller generates reset token
         ↓
PasswordResetMailer.reset_password(user).deliver_later
         ↓
Rails sends email to localhost:1025 (Mailpit)
         ↓
Mailpit captures email
         ↓
Email appears at http://localhost:8025
         ↓
User clicks link, resets password
```

## Production Setup (When Ready)

When deploying to production, add these environment variables:

```bash
SMTP_ADDRESS=smtp.sendgrid.net
SMTP_PORT=587
SMTP_USERNAME=your_username
SMTP_PASSWORD=your_password
MAILER_FROM_ADDRESS=noreply@yourdomain.com
```

Common SMTP providers:
- **SendGrid** - Free tier: 100 emails/day
- **Mailgun** - Free tier: 5,000 emails/month  
- **Postmark** - Free tier: 100 emails/month
- **AWS SES** - $0.10 per 1,000 emails

Then update `config/environments/production.rb`:
```ruby
config.action_mailer.smtp_settings = {
  address: ENV['SMTP_ADDRESS'],
  port: ENV['SMTP_PORT'],
  user_name: ENV['SMTP_USERNAME'],
  password: ENV['SMTP_PASSWORD'],
  authentication: 'plain',
  enable_starttls_auto: true
}
```

## Available Commands

```bash
task docker:up              # Start PostgreSQL + Mailpit
task mailpit                # Open Mailpit in browser
task docker:logs:mailpit    # View Mailpit logs
docker compose restart mailpit   # Restart Mailpit
```

## Testing Tips

1. **Keep Mailpit open** while developing - emails appear instantly
2. **Test different email clients** - Mailpit shows HTML and text versions
3. **Test email expiration** - Reset tokens expire after 2 hours
4. **Test invalid emails** - Try resetting with non-existent email
5. **Test email formatting** - Check responsive design in Mailpit

## Troubleshooting

### Emails not appearing?

**Check Mailpit is running:**
```bash
docker compose ps
```

**Check Rails logs:**
```bash
tail -f log/development.log
```

Look for:
```
Sent mail to user@example.com (1.2ms)
```

**Restart services:**
```bash
task docker:down
task docker:up
```

### Can't access Mailpit web UI?

**Check the URL:**
```
http://localhost:8025
```

**Check port isn't in use:**
```bash
lsof -i :8025
```

**Check Docker logs:**
```bash
task docker:logs:mailpit
```

## Security Notes

### Development (Current)
- Emails are captured locally
- Never sent to real addresses
- Perfect for testing
- No email quota concerns

### Production (Future)
- Use real SMTP provider
- Secure credentials with environment variables
- Enable TLS/SSL
- Monitor email delivery
- Set up SPF/DKIM records

## Next Steps

1. ✅ Email system is complete and working
2. Test the password reset flow thoroughly
3. When deploying, configure production SMTP
4. Consider adding:
   - Welcome email for new users
   - Email verification for signups
   - Notification emails for important events
