+# Deployment Checklist and Next Steps
+
+This document provides a checklist for deploying the multi-tenant POP3 Forwarder with web interface.
+
+## 🚀 Pre-Deployment Checklist
+
+### 1. Environment Setup
+
+#### Backend Environment Variables (`backend/.env`)
+- [ ] Generate secure `SECRET_KEY` (min 32 characters)
+  ```bash
+  openssl rand -hex 32
+  ```
+- [ ] Generate secure `ENCRYPTION_KEY` (min 32 characters)
+  ```bash
+  openssl rand -hex 32
+  ```
+- [ ] Set `DATABASE_URL` to production PostgreSQL instance
+- [ ] Configure `REDIS_URL` for production Redis
+- [ ] Set `CORS_ORIGINS` to include production frontend URL
+- [ ] Set `DEBUG=false` for production
+- [ ] Configure `LOG_LEVEL=INFO` or `WARNING`
+
+#### Google OAuth (Optional but Recommended)
+- [ ] Create Google Cloud Project
+- [ ] Enable Google+ API
+- [ ] Create OAuth 2.0 credentials
+- [ ] Set authorized redirect URIs:
+  - Development: `http://localhost:3000/auth/callback`
+  - Production: `https://yourdomain.com/auth/callback`
+- [ ] Add `GOOGLE_CLIENT_ID` to backend/.env
+- [ ] Add `GOOGLE_CLIENT_SECRET` to backend/.env
+- [ ] Add `GOOGLE_REDIRECT_URI` to backend/.env
+
+#### Frontend Environment Variables (`frontend/.env.local`)
+- [ ] Set `NEXT_PUBLIC_API_URL` to backend URL
+  - Development: `http://localhost:8000`
+  - Production: `https://api.yourdomain.com`
+
+### 2. Infrastructure Setup
+
+#### Docker Host
+- [ ] Server with Docker installed (20.10+)
+- [ ] Docker Compose installed (v2.0+)
+- [ ] Minimum 2 vCPU, 4GB RAM
+- [ ] 40GB+ available disk space

+### 3. SSL/TLS Configuration
+
+#### Option A: Let's Encrypt with Certbot
+```bash
+sudo apt-get install certbot python3-certbot-nginx
+sudo certbot --nginx -d yourdomain.com -d api.yourdomain.com
+```
+

+
+## 📦 Deployment Steps
+
+### Step 1: Clone Repository
+
+```bash
+# On production server
+cd /opt
+sudo git clone https://github.com/christianlouis/pop_puller_to_gmail.git
+cd pop_puller_to_gmail
+```
+
+### Step 2: Configure Environment
+
+```bash
+# Backend
+cd backend
+cp .env.example .env
+nano .env  # Edit with production values
+
+# Frontend
+cd ../frontend
+echo "NEXT_PUBLIC_API_URL=https://api.yourdomain.com" > .env.local
+```
+
+### Step 3: Build and Start Services
+
+```bash
+cd ..
+docker-compose -f docker-compose.new.yml build
+docker-compose -f docker-compose.new.yml up -d
+```
+
+### Step 4: Initialize Database
+
+```bash
+# Run migrations
+docker-compose -f docker-compose.new.yml exec backend alembic upgrade head
+
+# Verify
+docker-compose -f docker-compose.new.yml exec backend alembic current
+```
+
+### Step 5: Verify Services
+
+```bash
+# Check all services are running
+docker-compose -f docker-compose.new.yml ps
+
+# Check logs
+docker-compose -f docker-compose.new.yml logs -f
+```
+
+### Step 6: Test Application
+
+```bash
+# Test backend API
+curl https://api.yourdomain.com/health
+
+# Test frontend
+curl https://yourdomain.com
+
+# Register test user
+curl -X POST https://api.yourdomain.com/api/v1/auth/register \
+  -H "Content-Type: application/json" \
+  -d '{"email":"test@example.com","password":"testpass123","full_name":"Test User"}'
+```
+
+### Step 7: Configure Monitoring
+
+#### Health Checks
+```bash
+# Add to crontab for monitoring
+*/5 * * * * curl -f https://yourdomain.com/health || mail -s "Site Down" admin@yourdomain.com
+```
+
+#### Log Rotation
+```bash
+# Configure Docker log rotation in /etc/docker/daemon.json
+{
+  "log-driver": "json-file",
+  "log-opts": {
+    "max-size": "10m",
+    "max-file": "3"
+  }
+}
+```
+
+## 🔄 Maintenance
+
+### Regular Tasks
+
+#### Daily
+- [ ] Monitor error logs
+- [ ] Check Celery worker status
+- [ ] Verify email processing is working
+
+#### Weekly
+- [ ] Review database size and performance
+- [ ] Check for security updates
+- [ ] Rotate logs if necessary
+
+#### Monthly
+- [ ] Database backup verification
+- [ ] Review user feedback and errors
+- [ ] Update dependencies if needed
+
+### Backup Strategy
+
+#### Database Backups
+```bash
+# Automated daily backup script
+cat > /usr/local/bin/backup-pop3-db.sh << 'EOF'
+#!/bin/bash
+BACKUP_DIR=/var/backups/pop3_forwarder
+DATE=$(date +%Y%m%d_%H%M%S)
+docker exec pop3-postgres pg_dump -U postgres pop3_forwarder | gzip > $BACKUP_DIR/backup_$DATE.sql.gz
+find $BACKUP_DIR -type f -mtime +30 -delete
+EOF
+
+chmod +x /usr/local/bin/backup-pop3-db.sh
+
+# Add to crontab
+0 2 * * * /usr/local/bin/backup-pop3-db.sh
+```
+
+## 🐛 Troubleshooting
+
+### Common Issues
+
+#### Frontend Cannot Connect to Backend
+**Symptoms**: CORS errors, network errors
+**Solutions**:
+1. Verify `CORS_ORIGINS` includes frontend URL
+2. Check backend is accessible from frontend container
+3. Verify API URL in frontend .env.local
+
+#### Database Connection Errors
+**Symptoms**: "Connection refused" or timeout errors
+**Solutions**:
+1. Check PostgreSQL is running
+2. Verify DATABASE_URL is correct
+3. Check network connectivity
+4. Review PostgreSQL logs
+
+#### Celery Workers Not Processing
+**Symptoms**: Emails not being forwarded
+**Solutions**:
+1. Check Redis is running
+2. Review celery-worker logs
+3. Verify CELERY_BROKER_URL is correct
+4. Restart celery-worker container
+
+#### OAuth Not Working
+**Symptoms**: "Invalid redirect URI" or OAuth errors
+**Solutions**:
+1. Verify GOOGLE_REDIRECT_URI matches exactly
+2. Check OAuth credentials in Google Console
+3. Ensure HTTPS is used in production
+
+### Log Locations
+
+```bash
+# Backend logs
+docker-compose -f docker-compose.new.yml logs backend
+
+# Frontend logs
+docker-compose -f docker-compose.new.yml logs frontend
+
+# Celery worker logs
+docker-compose -f docker-compose.new.yml logs celery-worker
+
+# Database logs
+docker-compose -f docker-compose.new.yml logs postgres
+```
