 ## Architecture Overview
 
-This is a containerized mailing list management system built around Postfix as an SMTP relay through Amazon SES. **Currently in Phase 1** with static configuration; **planned expansion** includes web frontend and SQL database for dynamic member management.
+This is a complete containerized mailing list management system with four services:
 
-**Current Components (Phase 1):**
+1. **Web Frontend** (Port 3000) - Nginx serving modern HTML/CSS/JS interface
-- `docker-compose.yaml`: Single-service orchestration with SES credentials
+2. **REST API** (Port 8000) - FastAPI backend with token authentication  
-- `postfix/`: Complete Postfix container configuration  
+3. **MySQL Database** (Internal) - Stores lists, members, and subscriptions
-- Static virtual aliases system for mailing list distribution
+4. **Postfix Mail Server** (Port 25) - SMTP server with native MySQL integration
 
-**Planned Architecture (Phase 2+):**
+**Key Architecture Principles:**
-- Web frontend for list management (view/add/remove members)
+- Real-time operation: Changes take effect immediately without Postfix reload
-- SQL database backend for member storage
+- Native integration: Postfix queries MySQL directly (no Python scripts)
-- Dynamic Postfix configuration generation
+- Security-first: Private Docker network, token auth, sender whitelist
-- Multi-service Docker Compose setup
+- User-friendly: Web interface for easy management by non-technical users
 
 ## Configuration Pattern
 
-**Current (Static):** Environment variable substitution for secure credential management:
+**Dynamic Database-Driven Architecture:**
 
-1. **Credentials Flow**: SES credentials passed via environment → `sasl_passwd.template` → runtime generation in `entrypoint.sh`
+1. **Data Flow**: Web UI → REST API → MySQL ← Postfix (real-time queries)
-2. **Config Files**: Static configs (`main.cf`, `virtual_aliases.cf`) + dynamic SASL auth file
+2. **Credentials**: All sensitive data in `.env` file (SES, MySQL, API_TOKEN)
-3. **Postfix Maps**: Hash databases generated at build time (virtual aliases) and runtime (SASL)
+3. **Mail Processing**: 
+   - Email arrives for `list@lists.sasalliance.org`
+   - Postfix queries MySQL via `mysql_virtual_alias_maps.cf`
+   - MySQL returns comma-separated member emails
+   - Postfix expands alias and delivers via SES
+4. **Security**: Private Docker network (maillist-internal), sender whitelist (@sasalliance.org)
 
-**Future (Dynamic):** Database-driven configuration:
+**No Static Configuration:**
-- Member lists stored in SQL database, with members able to join multiple lists
+- Virtual aliases are stored in MySQL database, not config files
-- Web interface for CRUD operations on members
+- Changes take effect immediately without container restarts
-- `virtual_aliases.cf` generated from database at runtime
+- Postfix caches query results for performance
-- Postfix reload triggered by configuration changes
 
 ## Key Files and Their Roles
 
-- `main.cf`: Core Postfix config - relay through SES, domain settings, security
+### Docker & Environment
-- `sasl_passwd.template`: Template for SES authentication (uses `${SES_USER}:${SES_PASS}`)
+- `docker-compose.yaml`: Multi-service orchestration (mysql, postfix, api, web)
-- `virtual_aliases.cf`: Static email forwarding rules (one mailing list currently)
+- `.env`: All credentials and configuration (SES, MySQL, API_TOKEN)
-- `entrypoint.sh`: Runtime credential processing and Postfix startup
+
+### Web Frontend (`web/`)
+- `index.html`: Single-page application interface
+- `static/js/api.js`: API client with authentication
+- `static/js/ui.js`: UI helpers and modal management
+- `static/js/app.js`: Main application controller
+- `static/css/style.css`: Complete styling system
+- `nginx.conf`: Nginx configuration for static file serving
+
+### REST API (`api/`)
+- `main.py`: FastAPI application with all CRUD endpoints
+- `requirements.txt`: Python dependencies (fastapi, mysql-connector-python, etc.)
+- `Dockerfile`: Python 3.11 container build
+
+### Database (`database/`)
+- `schema.sql`: Database initialization with tables and sample data
+- Tables: `lists`, `members`, `list_members` (many-to-many junction)
+
+### Postfix (`postfix/`)
+- `main.cf.template`: Core Postfix config with MySQL virtual alias maps
+- `mysql_virtual_alias_maps.cf`: Native Postfix MySQL query configuration
+- `sender_access`: Sender whitelist (sasalliance.org domain allowed)
+- `sasl_passwd.template`: SES authentication template
+- `entrypoint.sh`: Container startup with MySQL health check and config generation
 
 ## Development Workflows
 
 **Building and Running:**
+
+Always use sudo for Docker commands. Don't bother opening the simple browser UI for Docker as it is not very useful.
+
 ```bash
-docker-compose up --build    # Build and start mail server
+sudo docker-compose up --build    # Build and start all services
-docker-compose logs -f       # Monitor mail delivery logs
+sudo docker-compose logs -f       # Monitor all service logs
+sudo docker-compose logs -f api   # Monitor specific service
 ```
 
-**Adding Mailing Lists (Current):**
+**Managing Lists and Members:**
-1. Edit `virtual_aliases.cf` with new list → recipients mapping
-2. Rebuild container (postmap runs at build time)
-3. No restart needed for existing virtual alias changes
 
-**Future Web Interface Workflow:**
+**Via Web Interface (Recommended):**
-1. Access web frontend at configured port
+1. Open http://localhost:3000
-2. Use CRUD interface to manage mailing lists and members
+2. Enter API_TOKEN from .env file
-3. Changes automatically update database and regenerate Postfix configs
+3. Use intuitive interface to manage lists, members, and subscriptions
+4. Click "Subscriptions" button on any member for toggle-based subscription management
+
+**Via REST API:**
+```bash
+# Get all lists
+curl -H "Authorization: Bearer $API_TOKEN" http://localhost:8000/lists
+
+# Create new list
+curl -X POST http://localhost:8000/lists \
+  -H "Authorization: Bearer $API_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"list_name":"Test","list_email":"test@lists.sasalliance.org","active":true}'
+
+# Subscribe member to list
+curl -X POST http://localhost:8000/subscriptions \
+  -H "Authorization: Bearer $API_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"list_email":"test@lists.sasalliance.org","member_email":"user@example.com"}'
+```
+
+**Via Direct Database Access:**
+```bash
+docker-compose exec mysql mysql -u maillist -p maillist
+# See database/README.md for SQL examples
+```
 
 **Testing Mail Delivery:**
 ```bash
 # From inside container
+docker-compose exec postfix bash
 echo "Test message" | mail -s "Subject" community@lists.sasalliance.org
 
 # Check logs for SES relay status
 docker-compose logs postfix | grep -E "(sent|bounced|deferred)"
+
+# Verify MySQL query works
+docker-compose exec postfix postmap -q "community@lists.sasalliance.org" \
+  mysql:/etc/postfix/mysql_virtual_alias_maps.cf
 ```
 
 ## Security Considerations
 
-- SES credentials exposed in docker-compose.yaml (consider using Docker secrets)
+- All credentials stored in `.env` file (git-ignored)
+- MySQL on private Docker network (no host port mapping)
+- API requires Bearer token authentication
+- Sender whitelist restricts who can send to lists (@sasalliance.org only)
 - SASL password file permissions set to 600 in entrypoint
 - TLS encryption enforced for SES relay (`smtp_tls_security_level = encrypt`)
-- Only localhost and configured hostname accepted for local delivery
+- Web interface requires token for all operations
 
 ## Configuration Conventions
 
 - **Hostname Pattern**: `lists.sasalliance.org` for mailing lists, origin domain `sasalliance.org`
-- **Virtual Aliases**: Simple format `listname@lists.domain → recipient1, recipient2`
+- **Virtual Aliases**: Dynamically queried from MySQL database in real-time
 - **SES Region**: EU West 2 (`email-smtp.eu-west-2.amazonaws.com`)
 - **Port Mapping**: Standard SMTP port 25 exposed to host
+- **Database Tables**: `lists`, `members`, `list_members` (many-to-many design)
+- **API Port**: 8000 for REST API
+- **Web Port**: 3000 for web interface
 
 ## Common Modifications
 
-**Adding Recipients to Existing List (Current):**
+**Adding Recipients to a List:**
-Edit `virtual_aliases.cf`, add comma-separated emails, rebuild container.
+Use web interface or API - changes are immediate!
 
-**New Mailing List (Current):**
+**Creating New Mailing List:**
-Add line to `virtual_aliases.cf`: `newlist@lists.sasalliance.org recipients...`
+1. Via Web: Click "Add List" button, fill in form
+2. Via API: POST to /lists endpoint with list details
+3. Via MySQL: INSERT into lists table
+
+**Adding New Member:**
+1. Via Web: Click "Add Member" button in Members tab
+2. Via API: POST to /members endpoint
+3. Via MySQL: INSERT into members table
+
+**Managing Subscriptions:**
+1. Via Web: Click "Subscriptions" button on member, toggle lists
+2. Via API: POST/DELETE to /subscriptions endpoint
+3. Via MySQL: INSERT/DELETE in list_members table
 
 **Credential Updates:**
-Update `SES_USER`/`SES_PASS` in docker-compose.yaml, restart container.
+1. Edit `.env` file with new credentials
-
+2. Restart affected services:
-## Migration Considerations
+   - SES: `docker-compose restart postfix`
-
+   - MySQL: `docker-compose restart mysql`
-When implementing the web frontend and database backend:
+   - API: `docker-compose restart api`
-- Preserve existing `community@lists.sasalliance.org` list during migration
-- Consider migration script to import current virtual aliases into database
-- Plan for zero-downtime deployment with database-driven config generation
-- Web interface should validate email addresses and handle duplicate members

+# SES SNS Bounce Handling Setup (Optional)
+
+**⚠️ NOTICE: Bounce handling is optional and disabled by default.**
+
+This document describes how to configure AWS SES and SNS to handle email bounces automatically in the Mail List Manager.
+
+**Prerequisites:**
+- SES production access (not available in sandbox mode)
+- Valid HTTPS domain for webhook endpoint
+- Bounce handling must be enabled in configuration
+
+## Overview
+
+The system can optionally use AWS Simple Notification Service (SNS) to receive real-time bounce notifications from AWS Simple Email Service (SES). When bounce handling is enabled and an email bounces:
+
+1. SES sends a notification to an SNS topic
+2. SNS forwards the notification to your webhook endpoint
+3. The API processes the notification and updates the database
+4. Members with hard bounces are automatically deactivated
+5. Bounce history is tracked and displayed in the UI
+
+## Bounce Status Types
+
+- **Clean**: No bounces recorded
+- **Soft Bounce**: Temporary delivery issues (e.g., mailbox full, temporary server issues)
+  - After 3 soft bounces, the member is marked with soft bounce status
+- **Hard Bounce**: Permanent delivery failure (e.g., invalid email address, domain doesn't exist)
+  - Member is automatically deactivated and cannot receive emails
+
+## Setup Instructions
+
+### 1. Enable Bounce Handling
+
+First, enable bounce handling in your `.env` file:
+
+```bash
+# Enable SNS webhook bounce handling
+ENABLE_SNS_WEBHOOKS=true
+ENABLE_BOUNCE_HANDLING=true
+```
+
+Restart the API container after making this change:
+```bash
+sudo docker-compose restart api
+```
+
+### 2. Prerequisites
+
+- AWS account with SES configured and verified
+- Your Mail List Manager deployed and accessible via HTTPS (required for SNS webhook)
+- Domain or subdomain for webhook (e.g., `https://lists.yourdomain.com`)
+
+### 3. Create SNS Topic
+
+1. Log in to AWS Console and navigate to SNS
+2. Click "Create topic"
+3. Choose "Standard" topic type
+4. Name: `ses-bounce-notifications` (or your preferred name)
+5. Display name: `SES Bounce Notifications`
+6. Click "Create topic"
+7. **Save the Topic ARN** (you'll need it in step 4) arn:aws:sns:eu-west-2:827164363113:ses-bounces
+
+### 4. Subscribe Your Webhook to SNS Topic
+
+1. In the SNS topic details, click "Create subscription"
+2. Protocol: `HTTPS`
+3. Endpoint: `https://yourdomain.com:8000/webhooks/sns`
+   - Replace `yourdomain.com` with your actual domain
+   - The API must be accessible via HTTPS (SNS doesn't support HTTP)
+4. Enable raw message delivery: **Unchecked**
+5. Click "Create subscription"
+6. The subscription will be in "PendingConfirmation" status
+
+### 5. Confirm SNS Subscription
+
+When you create the subscription, SNS will send a `SubscriptionConfirmation` request to your webhook endpoint. The Mail List Manager API automatically confirms this subscription.
+
+1. Check your API logs:
+   ```bash
+   sudo docker-compose logs -f api
+   ```
+2. You should see a log entry indicating the subscription was confirmed
+3. In the AWS SNS console, refresh the subscriptions list
+4. The status should change from "PendingConfirmation" to "Confirmed"
+
+### 6. Configure SES to Send Bounce Notifications
+
+1. Navigate to AWS SES console
+2. Go to "Configuration Sets" (or "Verified identities" > select your domain > "Notifications")
+3. For configuration sets:
+   - Create a new configuration set or select existing
+   - Add "Event destination"
+   - Event types: Select **"Bounce"** (and optionally "Complaint")
+   - Destination: SNS topic
+   - Select your SNS topic created in step 2
+4. For verified identities:
+   - Select your sending domain/email
+   - Click "Edit" in the "Notifications" section
+   - Bounce feedback: Select your SNS topic
+   - Include original headers: Enabled (optional)
+   - Click "Save changes"
+
+### 7. Verify Setup
+
+#### Test with a Bounce Simulator
+
+AWS SES provides bounce simulator addresses:
+
+```bash
+# From inside Postfix container
+docker-compose exec postfix bash
+echo "Test bounce" | mail -s "Test" bounce@simulator.amazonses.com
+```
+
+Or send to your mailing list with a test recipient:
+
+1. Add `bounce@simulator.amazonses.com` as a member
+2. Subscribe to a test list
+3. Send an email to the list
+
+#### Check the Results
+
+1. Wait a few minutes for SES to process and send the notification
+2. Check API logs:
+   ```bash
+   sudo docker-compose logs api | grep -i bounce
+   ```
+3. Log in to the web UI
+4. Go to Members tab
+5. Find the test member and click the "Bounces" button
+6. You should see the bounce event recorded
+
+### 8. Security Considerations
+
+#### SNS Signature Verification
+
+The webhook endpoint automatically verifies SNS message signatures to ensure notifications are genuine AWS messages. This prevents unauthorized parties from sending fake bounce notifications.
+
+#### HTTPS Requirement
+
+SNS requires HTTPS for webhooks. You'll need:
+- Valid SSL/TLS certificate for your domain
+- Reverse proxy (e.g., Nginx, Apache) in front of the API container
+- Or use AWS API Gateway as a proxy
+
+#### Example Nginx Configuration
+
+```nginx
+server {
+    listen 443 ssl http2;
+    server_name lists.yourdomain.com;
+    
+    ssl_certificate /path/to/cert.pem;
+    ssl_certificate_key /path/to/key.pem;
+    
+    # Webhook endpoint
+    location /webhooks/sns {
+        proxy_pass http://localhost:8000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+    
+    # Optional: proxy API for web UI
+    location /api {
+        proxy_pass http://localhost:8000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+```
+
+### 9. Managing Bounces in the UI
+
+#### View Bounce Status
+
+In the Members tab, bounced emails are indicated with:
+- Warning badge showing bounce count
+- Color-coded status (yellow for soft bounce, red for hard bounce)
+- Last bounce timestamp
+
+#### View Bounce History
+
+1. Click the "Bounces" button next to a member
+2. View detailed bounce history including:
+   - Bounce type (Permanent, Transient, Undetermined)
+   - Bounce subtype
+   - Diagnostic code from the receiving mail server
+   - Timestamp of each bounce
+
+#### Reset Bounce Status
+
+If a member's email has been corrected or verified:
+
+1. Open the bounce history modal
+2. Click "Reset Bounce Status"
+3. Confirm the action
+4. The member's bounce count is cleared and they can receive emails again
+
+**Note**: Only users with write access (administrators and operators) can reset bounce status.
+
+### 10. Monitoring and Maintenance
+
+#### Check Bounce Logs
+
+```bash
+# View all bounces in database
+sudo docker-compose exec mysql mysql -u maillist -p maillist -e "SELECT * FROM bounce_logs ORDER BY timestamp DESC LIMIT 20;"
+
+# Count bounces by type
+sudo docker-compose exec mysql mysql -u maillist -p maillist -e "SELECT bounce_type, COUNT(*) as count FROM bounce_logs GROUP BY bounce_type;"
+
+# Find members with bounces
+sudo docker-compose exec mysql mysql -u maillist -p maillist -e "SELECT name, email, bounce_count, bounce_status FROM members WHERE bounce_count > 0;"
+```
+
+#### API Health Check
+
+```bash
+# Check if webhook is accessible
+curl -X POST https://yourdomain.com:8000/webhooks/sns \
+  -H "Content-Type: application/json" \
+  -d '{"Type":"test"}'
+```
+
+#### Clean Up Old Bounce Records
+
+Periodically review and clean up old bounce records:
+
+```sql
+-- Delete bounce logs older than 90 days
+DELETE FROM bounce_logs WHERE created_at < DATE_SUB(NOW(), INTERVAL 90 DAY);
+```
+
+## Troubleshooting
+
+### SNS Subscription Not Confirming
+
+- Ensure the API container is running and accessible via HTTPS
+- Check API logs for errors
+- Verify firewall rules allow HTTPS traffic to port 8000
+- Test the endpoint manually: `curl https://yourdomain.com:8000/health`
+
+### Bounces Not Being Recorded
+
+1. Verify SNS topic is receiving messages:
+   - Check SNS topic metrics in AWS Console
+2. Verify subscription is active:
+   - Check subscription status in SNS console
+3. Check API logs for webhook errors:
+   ```bash
+   sudo docker-compose logs api | grep -i "sns\|bounce"
+   ```
+4. Test signature verification:
+   - Temporarily add debug logging to the webhook endpoint
+
+### Members Not Being Deactivated
+
+- Check if bounce type is "Permanent"
+- Review member's bounce_status in database:
+  ```bash
+  sudo docker-compose exec mysql mysql -u maillist -p maillist -e "SELECT * FROM members WHERE email='problem@example.com';"
+  ```
+- Verify bounce processing logic in API logs
+
+### SSL Certificate Issues
+
+If using self-signed certificates, SNS will reject the webhook. You must use:
+- Valid certificate from a trusted CA (Let's Encrypt, etc.)
+- Or use AWS Certificate Manager with API Gateway

+# Code Review Findings & Fixes
+
+## Date: 13 October 2025
+
+## Critical Issues Found and Fixed
+
+### 1. ✅ FIXED: Header Merging Bug in API Client
+**Severity:** HIGH  
+**Location:** `web/static/js/api.js` - `request()` method
+
+**Issue:**
+The header merging was incorrect. When passing custom headers in options, they were being overridden by the default headers due to incorrect spread operator order:
+
+```javascript
+// BEFORE (BUGGY):
+const config = {
+    headers: { ...this.headers },
+    ...options  // This overwrites headers!
+};
+```
+
+**Fix:**
+```javascript
+// AFTER (FIXED):
+const config = {
+    ...options,
+    headers: {
+        ...this.headers,
+        ...(options.headers || {})  // Custom headers take precedence
+    }
+};
+```
+
+**Impact:** 
+- The `login()` method was trying to remove the Authorization header for unauthenticated requests, but it was being overridden
+- Could have caused authentication issues or unexpected behavior
+
+---
+
+### 2. ✅ FIXED: Missing API Client Methods
+**Severity:** HIGH  
+**Location:** `web/static/js/api.js`
+
+**Issue:** Multiple methods were being called by the UI but didn't exist in the API client:
+- `login(username, password)` - ❌ Missing
+- `logout()` - ❌ Missing
+- `getCurrentUser()` - ❌ Missing
+- `getUsers()` - ❌ Missing
+- `createUser(userData)` - ❌ Missing
+- `updateUser(userId, userData)` - ❌ Missing
+- `deleteUser(userId)` - ❌ Missing
+- `getMemberBounces(memberId)` - ❌ Missing
+- `resetBounceStatus(memberId)` - ❌ Missing
+
+**Fix:** Added all missing methods with proper implementation
+
+---
+
+### 3. ✅ FIXED: Incorrect API Base URL for Production
+**Severity:** HIGH  
+**Location:** `web/static/js/api.js` - `getBaseURL()` method
+
+**Issue:**
+When running behind a reverse proxy (Caddy), the API client was trying to connect to `https://lists.sasalliance.org:8000` which:
+- Port 8000 is not exposed through Caddy
+- Would cause CORS issues
+- Would fail all API requests
+
+**Fix:**
+```javascript
+// Production detection
+if (hostname === 'localhost' || hostname === '127.0.0.1') {
+    return `${protocol}//${hostname}:8000`;  // Development
+}
+// Production - use reverse proxy path
+return `${protocol}//${hostname}/api`;
+```
+
+---
+
+## Potential Issues (Not Critical, But Worth Noting)
+
+### 4. ⚠️ CORS Configuration
+**Severity:** MEDIUM  
+**Location:** `api/main.py`
+
+**Current Configuration:**
+```python
+app.add_middleware(
+    CORSMiddleware,
+    allow_origins=["*"],  # Allows all origins
+    allow_credentials=True,
+    allow_methods=["*"],
+    allow_headers=["*"],
+)
+```
+
+**Issue:**
+- `allow_origins=["*"]` with `allow_credentials=True` is not allowed by browsers
+- Currently working because Caddy reverse proxy makes same-origin requests
+- If you ever need direct API access from different origins, this will fail
+
+**Recommendation:**
+```python
+# For production
+allow_origins=[
+    "https://lists.sasalliance.org",
+    "http://localhost:3000",  # For development
+],
+```
+
+---
+
+### 5. ✅ GOOD: Authentication Token Storage
+**Severity:** INFO  
+**Location:** `web/static/js/app.js`
+
+**Current Implementation:**
+```javascript
+localStorage.setItem('authToken', response.access_token);
+```
+
+**Assessment:**
+- ✅ Proper use of localStorage for JWT tokens
+- ✅ Token is cleared on logout
+- ✅ Token is validated on page load
+- ✅ Expired tokens trigger automatic logout
+
+**Note:** localStorage is appropriate for JWT tokens. HttpOnly cookies would be more secure but require different architecture.
+
+---
+
+### 6. ✅ GOOD: Error Handling
+**Severity:** INFO  
+**Location:** `web/static/js/ui.js` - `handleError()` method
+
+**Assessment:**
+- ✅ Proper handling of 401 (auth) errors with automatic logout
+- ✅ Proper handling of 403 (forbidden) errors
+- ✅ Proper handling of 404 (not found) errors
+- ✅ Proper handling of 500 (server) errors
+- ✅ User-friendly error messages
+
+---
+
+### 7. ✅ GOOD: Role-Based Access Control
+**Severity:** INFO  
+**Location:** Multiple files
+
+**Assessment:**
+- ✅ Backend enforces RBAC with decorators (`require_admin()`, `require_write_access()`, etc.)
+- ✅ Frontend checks user roles before showing UI elements
+- ✅ Three roles properly implemented: administrator, operator, read-only
+- ✅ UI elements are hidden/shown based on permissions
+
+---
+
+### 8. ⚠️ Token Expiration Handling
+**Severity:** LOW  
+**Location:** `api/main.py` and `web/static/js/app.js`
+
+**Current Configuration:**
+- JWT tokens expire in 30 minutes
+- Session records expire in 24 hours (but not enforced in JWT)
+
+**Potential Issue:**
+- Users will be logged out after 30 minutes without warning
+- No token refresh mechanism
+
+**Recommendation (Future Enhancement):**
+Consider implementing:
+- Token refresh endpoint
+- Warning before token expiration
+- Silent token refresh in background
+
+---
+
+### 9. ✅ GOOD: SQL Injection Prevention
+**Severity:** INFO  
+**Location:** `api/main.py`
+
+**Assessment:**
+- ✅ All SQL queries use parameterized statements with `%s` placeholders
+- ✅ No string concatenation in SQL queries
+- ✅ MySQL connector properly escapes parameters
+
+---
+
+### 10. ✅ GOOD: Password Security
+**Severity:** INFO  
+**Location:** `api/main.py`
+
+**Assessment:**
+- ✅ Uses bcrypt for password hashing (`passlib.context.CryptContext`)
+- ✅ Passwords are never stored in plain text
+- ✅ Passwords are never logged or exposed in API responses
+
+---
+
+## Testing Recommendations
+
+1. **Hard refresh browser cache** after updates (Ctrl+Shift+R)
+2. **Test authentication flow:**

+# Email-Based Bounce Handling Setup
+
+This document explains the email-based bounce handling system implemented as an alternative to SNS webhooks for environments without SES production access.
+
+## Overview
+
+The system processes email bounces directly within the Postfix container by:
+1. Rewriting return paths to direct bounces to a processing address
+2. Processing bounce emails via Python script
+3. Updating member bounce statistics in MySQL database
+4. Automatically disabling members with excessive bounces
+2. Setting up an alias that pipes bounce emails to a Python processing script
+3. The script parses bounce emails, extracts bounced addresses, and updates the database
+4. Members with hard bounces are automatically deactivated
+5. Bounce history is tracked and displayed in the UI (same as SNS method)
+
+## Advantages
+
+- **Works with SES Sandbox**: No production SES access required
+- **No External Dependencies**: Doesn't require SNS, webhooks, or HTTPS domains
+- **Self-Contained**: All processing happens within the existing containers
+- **Real-time Processing**: Bounces are processed as soon as emails arrive
+- **Compatible**: Uses the same database schema and UI as SNS bounce handling
+
+## Configuration
+
+### 1. Enable Email Bounce Processing
+
+In your `.env` file:
+
+```bash
+# Enable email-based bounce processing
+ENABLE_EMAIL_BOUNCE_PROCESSING=true
+
+# This will automatically enable bounce handling features
+ENABLE_BOUNCE_HANDLING=true  # Automatically set to true when email processing is enabled
+```
+
+### 2. Restart the System
+
+```bash
+sudo docker-compose down
+sudo docker-compose up --build -d
+```
+
+### 3. Verify Configuration
+
+Check that email bounce processing is enabled:
+
+```bash
+curl -s http://localhost:8000/config | jq .
+```
+
+Expected output:
+```json
+{
+  "bounce_handling_enabled": true,
+  "sns_webhooks_enabled": false,
+  "email_bounce_processing_enabled": true
+}
+```
+
+## How It Works
+
+### Postfix Configuration
+
+The system configures Postfix with:
+
+- `bounce_notice_recipient = bounces@lists.sasalliance.org`
+- `2bounce_notice_recipient = bounces@lists.sasalliance.org`
+- `error_notice_recipient = bounces@lists.sasalliance.org`
+
+### Aliases Configuration
+
+The `bounces` address is configured to pipe emails to the processing script:
+
+```
+bounces: "|/usr/local/bin/process-bounce.py"
+```
+
+### Bounce Processing Script
+
+The Python script (`/usr/local/bin/process-bounce.py`):
+
+1. **Reads bounce emails** from stdin (via pipe)
+2. **Parses email content** using multiple regex patterns to extract bounced addresses
+3. **Analyzes bounce type** based on SMTP error codes:
+   - 5xx codes = Permanent bounces
+   - 4xx codes = Transient bounces
+   - Unknown = Undetermined
+4. **Updates database** using the same schema as SNS bounce handling:
+   - Logs bounce in `bounce_logs` table
+   - Updates member `bounce_count`, `bounce_status`, and `last_bounce_at`
+   - Deactivates members with permanent bounces
+   - Marks members with soft bounce status after 3 transient bounces
+
+## Testing
+
+### Test the Processing Script
+
+You can test the bounce processing script in test mode:
+
+```bash
+# Test with sample bounce email
+sudo docker-compose exec postfix /usr/local/bin/process-bounce.py --test
+```
+
+Expected output:
+```
+2025-10-14 15:49:16,041 - bounce-processor - INFO - Starting bounce processing
+2025-10-14 15:49:16,041 - bounce-processor - INFO - Running in test mode with sample bounce email
+2025-10-14 15:49:16,050 - bounce-processor - INFO - Extracted addresses: ['testuser@example.com']
+2025-10-14 15:49:16,050 - bounce-processor - INFO - Test mode - would process 1 bounce(s):
+2025-10-14 15:49:16,050 - bounce-processor - INFO -   {'email': 'testuser@example.com', 'bounce_type': 'Permanent', 'bounce_subtype': 'General', 'diagnostic_code': '', 'timestamp': '2025-10-14 15:49:16'}
+```
+
+### Test with Real Bounce Email
+
+To test with a real bounce:
+
+1. Send an email to a non-existent address via your mailing list
+2. Wait for the bounce to be processed
+3. Check the database for bounce logs:
+
+```bash
+# Check bounce logs
+sudo docker-compose exec mysql mysql -u maillist -pmaillist maillist -e "SELECT * FROM bounce_logs ORDER BY created_at DESC LIMIT 5;"
+
+# Check member bounce status
+sudo docker-compose exec mysql mysql -u maillist -pmaillist maillist -e "SELECT member_id, email, bounce_count, bounce_status, last_bounce_at FROM members WHERE bounce_count > 0;"
+```
+
+### View in Web Interface
+
+1. Open http://localhost:3000
+2. Navigate to the Members tab
+3. Look for bounce badges and bounce counts next to member names
+4. Click the "Bounces" button next to a member to view bounce history
+
+## Supported Bounce Email Formats
+
+The processing script recognizes these bounce patterns:
+
+### SMTP Error Codes
+- 550, 551, 553, 552, 554 (permanent failures)
+- 450, 451, 452 (temporary failures)
+
+### Delivery Status Notification (DSN)
+- `Final-Recipient:` headers
+- `Original-Recipient:` headers
+
+### Common Bounce Messages
+- "user unknown"
+- "does not exist"
+- "not found"
+- "mailbox unavailable"
+- "recipient rejected"
+
+## Monitoring
+
+### View Processing Logs
+
+```bash
+# View bounce processing logs
+sudo docker-compose logs postfix | grep bounce-processor
+
+# Follow logs in real-time
+sudo docker-compose logs -f postfix | grep bounce-processor
+```
+
+### Check Aliases Configuration
+
+```bash
+# Verify aliases are configured correctly
+sudo docker-compose exec postfix cat /etc/aliases
+
+# Check alias database
+sudo docker-compose exec postfix postmap -q bounces /etc/aliases
+```
+
+## Troubleshooting
+
+### Bounces Not Being Processed
+
+1. **Check aliases configuration:**
+   ```bash
+   sudo docker-compose exec postfix cat /etc/aliases
+   ```
+
+2. **Verify script permissions:**
+   ```bash
+   sudo docker-compose exec postfix ls -la /usr/local/bin/process-bounce.py
+   ```
+
+3. **Test script manually:**
+   ```bash
+   sudo docker-compose exec postfix /usr/local/bin/process-bounce.py --test
+   ```
+
+4. **Check Postfix logs:**
+   ```bash
+   sudo docker-compose logs postfix | grep -i bounce
+   ```
+
+### Database Connection Issues
+
+1. **Check environment variables:**
+   ```bash
+   sudo docker-compose exec postfix env | grep MYSQL
+   ```
+
+2. **Test database connection:**
+   ```bash
+   sudo docker-compose exec postfix python3 -c "import pymysql; print('PyMySQL available')"
+   ```
+
+### Script Errors
+
+View detailed error logs:
+```bash
+sudo docker-compose logs postfix | grep -A 10 -B 10 "bounce-processor.*ERROR"
+```
+
+## Comparison with SNS Webhooks
+
+| Feature | Email-Based | SNS Webhooks |
+|---------|-------------|--------------|
+| **SES Requirement** | Sandbox OK | Production access required |
+| **External Dependencies** | None | SNS, HTTPS domain |
+| **Processing Speed** | Real-time | Real-time |
+| **Setup Complexity** | Low | High |
+| **Reliability** | High | High |
+| **Bounce Detection** | Regex-based | AWS-provided |
+| **Cost** | Free | SNS charges apply |
+
+## Next Steps
+
+1. **Monitor bounce processing** to ensure it's working correctly
+2. **Review bounce patterns** in the logs to improve detection if needed
+3. **Set up bounce notification alerts** (optional)
+4. **Consider upgrading to SNS webhooks** when SES production access is available
+
+Email-based bounce handling provides a robust alternative that works immediately with any SES configuration while providing the same bounce management features as the SNS webhook method.

+# Email-Based Bounce Handling Setup (Comprehensive)
+
+This document explains the complete email-based bounce handling system implemented as an alternative to SNS webhooks for environments without SES production access.
+
+## Overview
+
+The system processes email bounces directly within the Postfix container by:
+1. Rewriting return paths to direct bounces to a processing address
+2. Processing bounce emails via Python script  
+3. Updating member bounce statistics in MySQL database
+4. Automatically disabling members with excessive bounces
+
+## Configuration
+
+### Environment Variables (in .env)
+
+```bash
+# Bounce handling feature flags
+ENABLE_BOUNCE_HANDLING=true           # Master switch for bounce functionality
+ENABLE_EMAIL_BOUNCE_PROCESSING=true  # Enable email-based processing
+ENABLE_SNS_WEBHOOKS=false            # Disable SNS webhooks (optional)
+
+# Database settings (required for bounce processing)
+MYSQL_ROOT_PASSWORD=your_root_password
+MYSQL_DATABASE=maillist
+MYSQL_USER=maillist
+MYSQL_PASSWORD=your_maillist_password
+```
+
+### Key Components
+
+#### 1. Return Path Rewriting (`postfix/smtp_generic`)
+Routes all bounces to the processing address:
+```
+@lists.sasalliance.org    bounces@lists.sasalliance.org
+@sasalliance.org          bounces@lists.sasalliance.org
+```
+
+#### 2. Bounce Processing Script (`postfix/process-bounce.py`)
+Python script that:
+- Parses bounce emails for recipient addresses and bounce types
+- Updates bounce counts in MySQL database
+- Automatically disables members after 5 hard bounces
+- Logs all bounce events
+
+#### 3. Postfix Integration (`postfix/main.cf.template`)
+```
+# Return path rewriting for outbound mail
+smtp_generic_maps = hash:/etc/postfix/smtp_generic
+
+# Bounce processing
+bounce_notice_recipient = bounces@lists.sasalliance.org
+```
+
+#### 4. Email Aliases (`postfix/entrypoint.sh`)
+```
+# Route bounces to processing script
+bounces: "|/usr/local/bin/python3 /etc/postfix/process-bounce.py"
+```
+
+## How It Works
+
+### Outbound Email Flow
+1. User sends email to `community@lists.sasalliance.org`
+2. Postfix expands to member list via MySQL
+3. Email sent via SES with return path rewritten to `bounces@lists.sasalliance.org`
+4. If delivery fails, bounce goes to bounce processing address
+
+### Bounce Processing Flow
+1. Bounce email arrives at `bounces@lists.sasalliance.org`
+2. Postfix pipes email to `process-bounce.py` script
+3. Script parses bounce for recipient and bounce type
+4. Database updated with bounce information
+5. Member automatically disabled if hard bounce threshold reached
+
+### Bounce Types Detected
+- **Hard Bounces**: Permanent failures (5.x.x SMTP codes)
+  - Invalid email addresses
+  - Domain doesn't exist
+  - Mailbox doesn't exist
+- **Soft Bounces**: Temporary failures (4.x.x SMTP codes)  
+  - Mailbox full
+  - Temporary server issues
+  - Rate limiting
+
+## Database Schema
+
+### Bounce Logs Table
+```sql
+CREATE TABLE bounce_logs (
+    id INT PRIMARY KEY AUTO_INCREMENT,
+    email VARCHAR(255) NOT NULL,
+    bounce_type ENUM('hard', 'soft', 'complaint') NOT NULL,
+    bounce_reason TEXT,
+    bounced_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    raw_message TEXT,
+    INDEX idx_email (email),
+    INDEX idx_bounced_at (bounced_at)
+);
+```
+
+### Members Table (bounce tracking fields)
+```sql
+ALTER TABLE members ADD COLUMN bounce_count INT DEFAULT 0;
+ALTER TABLE members ADD COLUMN last_bounce_at TIMESTAMP NULL;
+ALTER TABLE members ADD COLUMN active BOOLEAN DEFAULT true;
+```
+
+## Testing Bounce Handling
+
+### 1. Test Return Path Configuration
+```bash
+# Check that return path rewriting is working
+sudo docker-compose exec postfix postconf smtp_generic_maps
+sudo docker-compose exec postfix postmap -q "test@lists.sasalliance.org" hash:/etc/postfix/smtp_generic
+```
+
+### 2. Simulate Bounce Email
+```bash
+# Send test bounce to processing script
+echo "Subject: Delivery Status Notification (Failure)
+From: MAILER-DAEMON@ses.amazonaws.com
+To: bounces@lists.sasalliance.org
+
+The following message could not be delivered:
+   Recipient: test@example.com
+   Reason: 550 5.1.1 User unknown" | docker-compose exec -T postfix mail -s "Test Bounce" bounces@lists.sasalliance.org
+```
+
+### 3. Check Bounce Processing
+```bash
+# View bounce logs
+sudo docker-compose exec mysql mysql -u maillist -pmaillist maillist -e "SELECT * FROM bounce_logs ORDER BY bounced_at DESC LIMIT 5;"
+
+# Check member bounce counts
+sudo docker-compose exec mysql mysql -u maillist -pmaillist maillist -e "SELECT email, bounce_count, last_bounce_at, active FROM members WHERE bounce_count > 0;"
+```
+
+## Monitoring and Maintenance
+
+### View Processing Logs
+```bash
+# Monitor bounce processing
+sudo docker-compose logs -f postfix | grep -E "(bounce|process-bounce)"
+
+# Check API bounce handling status
+curl -H "Authorization: Bearer $API_TOKEN" http://localhost:8000/config
+```
+
+### Reset Member Bounce Count
+```bash
+# Via API
+curl -X POST http://localhost:8000/members/{member_id}/reset-bounces \
+  -H "Authorization: Bearer $API_TOKEN"
+
+# Via Database
+sudo docker-compose exec mysql mysql -u maillist -pmaillist maillist -e "UPDATE members SET bounce_count=0, active=true WHERE email='user@example.com';"
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### Bounces Not Being Processed
+1. Check that `bounces` alias exists: `sudo docker-compose exec postfix cat /etc/aliases | grep bounces`
+2. Verify Python script permissions: `sudo docker-compose exec postfix ls -la /etc/postfix/process-bounce.py`
+3. Test script manually: `sudo docker-compose exec postfix python3 /etc/postfix/process-bounce.py --test`
+
+#### Return Path Not Rewritten
+1. Check smtp_generic configuration: `sudo docker-compose exec postfix postconf smtp_generic_maps`
+2. Verify map file exists: `sudo docker-compose exec postfix ls -la /etc/postfix/smtp_generic*`
+3. Test mapping: `sudo docker-compose exec postfix postmap -q "test@lists.sasalliance.org" hash:/etc/postfix/smtp_generic`
+
+#### Database Connection Issues
+1. Check PyMySQL installation: `sudo docker-compose exec postfix python3 -c "import pymysql; print('OK')"`
+2. Test database connection: `sudo docker-compose exec postfix python3 -c "import pymysql; pymysql.connect(host='mysql', user='maillist', password='your_password', database='maillist')"`
+3. Verify network connectivity: `sudo docker-compose exec postfix ping mysql`
+
+### Log Analysis
+```bash
+# Postfix logs
+sudo docker-compose logs postfix | grep -E "(bounce|MAILER-DAEMON|process-bounce)"
+
+# MySQL connection logs
+sudo docker-compose logs postfix | grep -E "(pymysql|mysql)"
+
+# SES relay logs
+sudo docker-compose logs postfix | grep -E "(relay|sent|deferred)"
+```
+
+## Security Considerations
+
+- Bounce processing script runs with limited privileges
+- Database credentials secured in environment variables
+- Bounce emails contain sensitive delivery information - logs are rotated
+- Return path rewriting prevents bounce loops
+- Processing script validates email format before database updates
+
+## Performance Notes
+
+- Bounce processing is asynchronous (doesn't block email delivery)
+- Database queries are indexed for bounce lookups
+- Bounce logs should be periodically archived for large volumes
+- SMTP generic maps are cached by Postfix for performance
+
+## Advantages over SNS Webhooks
+
+- **Works with SES Sandbox**: No production SES access required
+- **No External Dependencies**: Doesn't require SNS, webhooks, or HTTPS domains
+- **Self-Contained**: All processing happens within existing containers
+- **Real-time Processing**: Bounces processed as emails arrive
+- **Compatible**: Uses same database schema and UI as SNS method

 ## Configuration
 
-### Adding Mailing Lists (Current)
+### Managing Lists and Members
 
-Edit `postfix/virtual_aliases.cf`:
+**Via Web Interface (Recommended):**
-```
+1. Open http://localhost:3000
-newlist@lists.sasalliance.org   recipient1@domain.com, recipient2@domain.com
+2. Enter your API token
-```
+3. Use the intuitive interface to:
+   - Create/edit/delete mailing lists
+   - Add/edit/remove members
+   - Manage subscriptions with toggle switches
+   - View member counts and list details
 
-Then rebuild the container:
+**Via REST API:**
 ```bash
-docker-compose up --build
+# Create a new list
+curl -X POST http://localhost:8000/lists \
+  -H "Authorization: Bearer your_token" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "list_name": "Developers",
+    "list_email": "dev@lists.sasalliance.org",
+    "description": "Developer discussions",
+    "active": true
+  }'
+
+# Add a new member
+curl -X POST http://localhost:8000/members \
+  -H "Authorization: Bearer your_token" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "John Doe",
+    "email": "john@example.com",
+    "active": true
+  }'
+
+# Subscribe member to list
+curl -X POST http://localhost:8000/subscriptions \
+  -H "Authorization: Bearer your_token" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "list_email": "dev@lists.sasalliance.org",
+    "member_email": "john@example.com"
+  }'
 ```
 
-### Domain Configuration
+**Via Direct Database Access:**
+```bash
+# Connect to MySQL
+docker-compose exec mysql mysql -u maillist -p maillist
 
-The system is configured for:
+# Run SQL queries (see database/README.md for examples)
-- **Hostname**: `lists.sasalliance.org` (mailing lists)
+```
+
+### Mail Server Configuration
+
+### Mail Server Configuration
+
+The Postfix mail server is configured for:
+- **Hostname**: `lists.sasalliance.org` (accepts mail for this domain)
 - **Origin Domain**: `sasalliance.org`
 - **SES Region**: EU West 2 (configurable via `SMTP_HOST`)
+- **Sender Whitelist**: @sasalliance.org (only authorized board members can send to lists)
+- **Dynamic Lists**: Postfix queries MySQL in real-time for list members
+
+### Testing Mail Delivery
+
+```bash
+# From inside Postfix container
+docker-compose exec postfix bash
+echo "Test message" | mail -s "Test Subject" community@lists.sasalliance.org
+
+# Check delivery logs
+docker-compose logs -f postfix | grep -E "(sent|bounced|deferred)"
+
+# Verify MySQL query works
+docker-compose exec postfix postmap -q "community@lists.sasalliance.org" \
+  mysql:/etc/postfix/mysql_virtual_alias_maps.cf
+```
+
+### Bounce Handling (Optional)
+
+**Email bounce handling is optional and disabled by default.**
+
+**Three Configuration Options:**
+
+1. **SNS Webhooks** (Requires SES Production Access):
+   ```bash
+   # In .env file
+   ENABLE_SNS_WEBHOOKS=true
+   ENABLE_BOUNCE_HANDLING=true
+   ```
+   - Real-time bounce notifications via AWS SNS webhooks
+   - Automatic member deactivation for hard bounces
+   - Bounce history tracking and management in web UI
+   - Requires valid HTTPS domain and SES production access
+   - See `BOUNCE_HANDLING_SETUP.md` for complete setup
+
+2. **Email-Based Processing** (Works with SES Sandbox):
+   ```bash
+   # In .env file
+   ENABLE_EMAIL_BOUNCE_PROCESSING=true
+   ENABLE_BOUNCE_HANDLING=true  # Automatically enabled
+   ```
+   - Automatic bounce processing via email parsing
+   - Same bounce management features as SNS webhooks
+   - Works with SES sandbox accounts (no production access needed)
+   - Self-contained processing within existing containers
+   - See `EMAIL_BOUNCE_HANDLING_SETUP.md` for complete setup
+
+3. **Disabled** (Manual Processing Only):
+   ```bash
+   # In .env file (or leave these commented out)
+   ENABLE_SNS_WEBHOOKS=false
+   ENABLE_BOUNCE_HANDLING=false
+   ENABLE_EMAIL_BOUNCE_PROCESSING=false
+   ```
+   - No automatic bounce processing
+   - Manual bounce management via email notifications
+   - Bounce-related UI elements are hidden
+
+**When bounce handling is disabled:**
+- `/webhooks/sns` endpoint is not registered
+- Bounce history endpoints return empty results
+- Web UI hides bounce badges and bounce management buttons
+- No automatic member deactivation occurs
 
 ## Security
 
-- SES credentials are stored in `.env` (git-ignored)
+- **Environment Variables**: All credentials stored in `.env` (git-ignored)
-- SASL password files have restricted permissions (600)
+- **Private Network**: MySQL communicates with Postfix/API on internal Docker network only
-- TLS encryption enforced for SES relay
+- **Token Authentication**: API requires Bearer token for all write operations
-- Only localhost and configured hostname accepted for local delivery
+- **Sender Whitelist**: Only @sasalliance.org addresses can send to mailing lists
+- **TLS Encryption**: Enforced for SES relay connections
+- **File Permissions**: SASL password files have restricted permissions (600)

+### Development Workflow
+
+1. **Make changes** to code or configuration
+2. **Rebuild affected service**:
+   ```bash
+   sudo docker-compose up --build -d web   # Just web frontend
+   sudo docker-compose up --build -d api   # Just API
+   sudo docker-compose up --build -d postfix  # Just mail server

+   ```
+4. **Test changes** via web interface or API
+
+### Common Tasks
+
+**Reset database completely:**
+```bash
+docker-compose down -v  # Removes volumes
+docker-compose up -d    # Reinitializes from schema.sql
+```
+
+**Update API token:**
+1. Edit `.env` and change `API_TOKEN`
+2. Restart API: `docker-compose restart api`
+3. Use new token in web interface
+
+**Add authorized sender domain:**
+1. Edit `postfix/sender_access`
+2. Add line: `newdomain.com    OK`
+3. Rebuild: `docker-compose up --build -d postfix`
+
+## How It Works
+
+1. **User manages lists** via web interface (http://localhost:3000)
+2. **Web frontend** makes authenticated API calls to FastAPI backend
+3. **API updates MySQL** database with new lists/members/subscriptions
+4. **Email arrives** at Postfix for `someone@lists.sasalliance.org`
+5. **Postfix queries MySQL** in real-time using native MySQL support
+6. **MySQL returns** comma-separated list of active member emails
+7. **Postfix expands** the alias and delivers to all members via SES
+8. **Changes take effect immediately** - no restart or reload needed!
+
+## Features
+
+- ✅ **Real-time Updates** - Changes to lists/members take effect immediately
+- ✅ **Native MySQL Integration** - Postfix queries database directly (no scripts)
+- ✅ **Web Interface** - Modern, responsive UI for easy management
+- ✅ **REST API** - Complete programmatic access with token auth
+- ✅ **Sender Whitelist** - Only authorized domains can send to lists
+- ✅ **SES Integration** - Reliable email delivery through Amazon SES
+- ✅ **Bounce Handling** - Automatic tracking and management of email bounces via SNS
+- ✅ **Secure** - Private Docker network, token auth, environment-based credentials
+- ✅ **Flexible** - Manage via web, API, or direct database access
+- ✅ **Scalable** - Database-driven architecture supports many lists and members

+# Testing Bounces from SES Sandbox
+
+AWS SES provides **built-in bounce simulator addresses** that work even in sandbox mode. This guide shows you how to use them to test your bounce handling.
+
+## Quick Answer
+
+Send email to these special AWS addresses to simulate different bounce types:
+
+### Hard Bounce (Permanent - Invalid Address)
+```bash
+bounce@simulator.amazonses.com
+```
+
+### Soft Bounce (Temporary - Mailbox Full)
+```bash
+ooto@simulator.amazonses.com
+```
+
+### Complaint (Spam Report)
+```bash
+complaint@simulator.amazonses.com
+```
+
+### Successful Delivery (No Bounce)
+```bash
+success@simulator.amazonses.com
+```
+
+## Step-by-Step Testing Guide
+
+### Option 1: Using Your Mailing Lists (Recommended)
+
+This tests the complete flow: Postfix → SES → SNS → API
+
+1. **Add the simulator address as a member:**
+   ```bash
+   # Using the API
+   curl -X POST http://localhost:8000/members \
+     -H "Authorization: Bearer $API_TOKEN" \
+     -H "Content-Type: application/json" \
+     -d '{
+       "name": "Bounce Test",
+       "email": "bounce@simulator.amazonses.com",
+       "active": true
+     }'
+   ```
+
+   Or use the Web UI:
+   - Go to http://localhost:3000
+   - Members tab → Add Member
+   - Name: `Bounce Test`
+   - Email: `bounce@simulator.amazonses.com`
+
+2. **Subscribe to a test list:**
+   - Click "Subscriptions" button for the test member
+   - Toggle on one of your mailing lists
+
+3. **Send email to the list:**
+   ```bash
+   # From inside Postfix container
+   sudo docker compose exec postfix bash
+   echo "This will bounce" | mail -s "Test Bounce" community@lists.sasalliance.org
+   exit
+   ```
+
+   Replace `community@lists.sasalliance.org` with your actual list email.
+
+4. **Wait 30-60 seconds** for:
+   - Email to be sent via SES
+   - SES to process the bounce
+   - SNS to send notification to your webhook
+
+5. **Check the results:**
+
+   **Watch API logs in real-time:**
+   ```bash
+   sudo docker compose logs api -f
+   ```
+   
+   You should see:
+   ```
+   ============================================================
+   SNS Webhook Request Received
+   ============================================================
+   Content-Type: text/plain; charset=UTF-8
+   User-Agent: Amazon Simple Notification Service Agent
+   
+   ✓ Notification Received
+     Notification Type: Bounce
+   
+   ✓ Processing Bounce
+     Bounce Type: Permanent
+     Recipients: ['bounce@simulator.amazonses.com']
+     ✓ Bounce processed successfully
+   ============================================================
+   ```
+
+   **Check the database:**
+   ```bash
+   # View bounce logs
+   sudo docker compose exec mysql mysql -u maillist -pmaillist maillist \
+     -e "SELECT * FROM bounce_logs ORDER BY created_at DESC LIMIT 5;"
+   
+   # Check member status
+   sudo docker compose exec mysql mysql -u maillist -pmaillist maillist \
+     -e "SELECT email, active, bounce_count, bounce_status FROM members WHERE email='bounce@simulator.amazonses.com';"
+   ```
+
+   **View in Web UI:**
+   - Open http://localhost:3000
+   - Go to Members tab
+   - Find "Bounce Test" member
+   - Should show: ❌ Inactive (red), bounce badge, last bounce timestamp
+   - Click "Bounces" button to see detailed history
+
+### Option 2: Direct Email via Postfix (Simpler)
+
+Send directly to the simulator without going through your list:
+
+```bash
+# Enter Postfix container
+sudo docker compose exec postfix bash
+
+# Send test email
+echo "Testing hard bounce" | mail -s "Hard Bounce Test" bounce@simulator.amazonses.com
+
+# Or soft bounce
+echo "Testing soft bounce" | mail -s "Soft Bounce Test" ooto@simulator.amazonses.com
+
+# Exit container
+exit
+```
+
+### Option 3: Using AWS SES Console (For Non-Sandbox Testing)
+
+If you have SES production access:
+
+1. Go to AWS SES Console
+2. Click "Send test email"
+3. To: `bounce@simulator.amazonses.com`
+4. From: Your verified email/domain
+5. Subject: "Bounce test"
+6. Body: "Testing bounce handling"
+7. Click "Send test email"
+
+## Testing Different Bounce Types
+
+### 1. Hard Bounce (Permanent Failure)
+```bash
+echo "Test" | mail -s "Test" bounce@simulator.amazonses.com
+```
+
+**Expected Result:**
+- Member marked as `hard_bounce`
+- Member deactivated (`active = 0`)
+- `bounce_count` incremented
+- Entry in `bounce_logs` table
+
+### 2. Soft Bounce (Transient Failure)
+```bash
+echo "Test" | mail -s "Test" ooto@simulator.amazonses.com
+```
+
+**Expected Result:**
+- Member marked as `clean` (first time)
+- After 3 soft bounces → `soft_bounce` status
+- `bounce_count` incremented
+- Member stays active
+
+### 3. Complaint (Spam Report)
+```bash
+echo "Test" | mail -s "Test" complaint@simulator.amazonses.com
+```
+
+**Expected Result:**
+- API receives complaint notification
+- Currently logged but not processed (you can extend the handler)
+
+## Monitoring the Test
+
+### Real-Time Monitoring (Recommended)
+
+Open 3 terminal windows:
+
+**Terminal 1 - API Logs:**
+```bash
+sudo docker compose logs api -f
+```
+
+**Terminal 2 - Postfix Logs:**
+```bash
+sudo docker compose logs postfix -f
+```
+
+**Terminal 3 - Send Test Email:**
+```bash
+sudo docker compose exec postfix bash
+echo "Test" | mail -s "Bounce Test" bounce@simulator.amazonses.com
+```
+
+### Timeline
+
+Here's what happens and when:
+
+- **T+0s**: Email sent to Postfix
+- **T+1-3s**: Postfix relays to SES
+- **T+5-10s**: SES processes and generates bounce
+- **T+10-30s**: SNS sends notification to your webhook
+- **T+30-60s**: API processes bounce and updates database
+
+## Verifying the Complete Flow
+
+### 1. Check Postfix Logs
+```bash
+sudo docker compose logs postfix | grep bounce@simulator
+```
+
+Should show:
+```
+postfix/smtp[xxx]: ... to=<bounce@simulator.amazonses.com>, relay=email-smtp.eu-west-2.amazonaws.com[...], ... status=sent
+```
+
+### 2. Check SNS Subscription Status
+- Go to AWS SNS Console
+- Find your topic
+- Check "Subscriptions" tab
+- Status should be "Confirmed"
+- Messages delivered should be > 0
+
+### 3. Check API Logs
+```bash
+sudo docker compose logs api | grep -A 20 "SNS Webhook"
+```
+
+Should show successful processing.
+
+### 4. Check Database
+```bash
+sudo docker compose exec mysql mysql -u maillist -pmaillist maillist <<EOF
+-- Show recent bounces
+SELECT 
+    b.bounce_id,
+    m.email,
+    b.bounce_type,
+    b.diagnostic_code,
+    b.timestamp
+FROM bounce_logs b
+JOIN members m ON b.member_id = m.member_id
+ORDER BY b.timestamp DESC
+LIMIT 5;
+
+-- Show members with bounces
+SELECT 
+    email,
+    active,
+    bounce_count,
+    bounce_status,
+    last_bounce_at
+FROM members
+WHERE bounce_count > 0;
+EOF
+```
+
+## Troubleshooting
+
+### "Email not sent" or "Relay access denied"
+
+**Problem**: Postfix not configured to relay via SES
+
+**Check**:
+```bash
+sudo docker compose exec postfix postconf relayhost
+sudo docker compose exec postfix postconf smtp_sasl_auth_enable
+```
+
+Should show:
+```
+relayhost = [email-smtp.eu-west-2.amazonaws.com]:587
+smtp_sasl_auth_enable = yes
+```
+
+### "No bounce received after 5 minutes"
+
+**Possible causes**:
+
+1. **SNS subscription not confirmed**
+   - Check AWS SNS console
+   - Status should be "Confirmed", not "Pending"
+
+2. **SNS topic not configured in SES**
+   - Check SES → Configuration Sets or Verified Identities → Notifications
+   - Bounce notifications should point to your SNS topic
+
+3. **Webhook endpoint not accessible**
+   - SNS requires HTTPS
+   - Test: `curl https://your-domain.com:8000/health`
+
+4. **API container not running**
+   ```bash
+   sudo docker compose ps api
+   ```
+
+### "Bounce received but not in database"
+
+**Check API logs for errors**:
+```bash
+sudo docker compose logs api | grep -i error
+```
+
+**Check database tables exist**:
+```bash
+sudo docker compose exec mysql mysql -u maillist -pmaillist maillist -e "SHOW TABLES;"
+```
+
+Should include: `bounce_logs`, `members`
+
+## Testing Multiple Bounces
+
+To test the "3 soft bounces = soft_bounce status" logic:
+
+```bash
+sudo docker compose exec postfix bash
+
+# Send 3 emails to soft bounce simulator
+for i in {1..3}; do
+    echo "Soft bounce test $i" | mail -s "Test $i" ooto@simulator.amazonses.com
+    sleep 70  # Wait between sends for SNS processing
+done
+```
+
+After the 3rd bounce:
+- Member's `bounce_status` should change from `clean` to `soft_bounce`
+- `bounce_count` should be 3
+
+## Cleanup After Testing
+
+Remove test bounce data:
+
+```bash
+sudo docker compose exec mysql mysql -u maillist -pmaillist maillist <<EOF
+-- Delete test bounce logs
+DELETE FROM bounce_logs WHERE email IN ('bounce@simulator.amazonses.com', 'ooto@simulator.amazonses.com');
+
+-- Reset test member
+UPDATE members 
+SET bounce_count = 0, 
+    bounce_status = 'clean', 
+    last_bounce_at = NULL,
+    active = 1
+WHERE email IN ('bounce@simulator.amazonses.com', 'ooto@simulator.amazonses.com');
+EOF
+```
+
+Or use the Web UI:
+- Go to Members tab
+- Find the test member
+- Click "Bounces" button
+- Click "Reset Bounce Status"
+
+## Alternative: Simulate Bounces Without SES
+
+If SNS isn't set up yet, use the included script to simulate bounces directly in the database:
+
+```bash
+./simulate_bounce.sh
+```
+
+This is useful for:
+- Testing the UI without AWS
+- Development environments
+- Demonstrating bounce handling to stakeholders
+
+## Next Steps
+
+Once bounce handling is working:
+
+1. **Remove simulator addresses** from your member list
+2. **Monitor real bounces** in production
+3. **Set up alerts** for high bounce rates
+4. **Review bounced members** regularly and update/remove invalid addresses
+5. **Consider complaint handling** (similar to bounces, for spam reports)
+
+## Summary Commands
+
+**Quick test sequence**:
+```bash
+# 1. Watch logs
+sudo docker compose logs api -f &
+
+# 2. Send test bounce
+echo "Test" | sudo docker compose exec -T postfix mail -s "Bounce Test" bounce@simulator.amazonses.com
+
+# 3. Wait 60 seconds, then check database
+sleep 60
+sudo docker compose exec mysql mysql -u maillist -pmaillist maillist -e "SELECT * FROM bounce_logs ORDER BY created_at DESC LIMIT 1;"
+```
+
+That's it! The bounce simulator is the easiest way to test your bounce handling without needing real bounced emails.

+# SNS Webhook Debugging Guide
+
+## Current Status
+
+✅ **Detailed logging is now active!** The API will log all incoming SNS requests with:
+- Full headers (including SNS-specific headers)
+- Request body content
+- Parsed message structure
+- Processing steps and results
+
+## How to View Logs in Real-Time
+
+```bash
+# Watch API logs as SNS sends notifications
+sudo docker compose logs api -f
+```
+
+## Testing with Real AWS SNS
+
+### Step 1: Trigger a Test from SNS Console
+
+1. Go to AWS SNS Console → Your Topic
+2. Click "Publish message"
+3. Send a test notification
+
+### Step 2: Check the Logs
+
+The logs will show you exactly what SNS sent:
+
+```
+============================================================
+SNS Webhook Request Received
+============================================================
+Content-Type: text/plain; charset=UTF-8
+User-Agent: Amazon Simple Notification Service Agent
+X-Amz-SNS-Message-Type: Notification
+X-Amz-SNS-Topic-Arn: arn:aws:sns:...
+
+Message Type: Notification
+Message Keys: ['Type', 'MessageId', 'TopicArn', 'Message', ...]
+
+✓ Notification Received
+  Message (first 200 chars): {"notificationType":"Bounce",...
+  Notification Type: Bounce
+
+✓ Processing Bounce
+  Bounce Type: Permanent
+  Recipients: ['bounce@example.com']
+  ✓ Bounce processed successfully
+============================================================
+```
+
+## What the Logs Tell You
+
+### If you see this:
+- **"SNS webhook received body: b''"** → SNS sent empty body (check SNS configuration)
+- **"Missing SigningCertURL"** → Message missing required SNS fields
+- **"Invalid certificate URL"** → Certificate URL not from amazonaws.com
+- **"Invalid signature"** → Signature verification failed (message tampered or wrong cert)
+
+### Successful Flow:
+1. Headers logged → Shows SNS user agent and message type
+2. Body logged → Shows the raw JSON
+3. Message parsed → Shows the Type field
+4. Notification processed → Shows bounce/complaint details
+5. Database updated → Confirmation of processing
+
+## Understanding Previous Errors
+
+The error you saw earlier:
+```
+SNS webhook error: Expecting value: line 1 column 1 (char 0)
+```
+
+This means SNS was sending an **empty body** or the body was already consumed. Possible causes:
+1. SNS subscription confirmation URL was opened in a browser (GET request, not POST)
+2. Network issue causing body to be lost
+3. SNS configuration issue
+
+## Testing Bounce Handling
+
+### Option 1: AWS SES Bounce Simulator
+Send email to: `bounce@simulator.amazonses.com`
+
+### Option 2: Verify Database Updates
+After a bounce is processed:
+
+```bash
+# Check bounce logs
+sudo docker compose exec mysql mysql -u maillist -pmaillist maillist -e "SELECT * FROM bounce_logs ORDER BY created_at DESC LIMIT 5;"
+
+# Check member bounce status
+sudo docker compose exec mysql mysql -u maillist -pmaillist maillist -e "SELECT member_id, email, bounce_count, bounce_status, last_bounce_at FROM members WHERE bounce_count > 0;"
+```
+
+## Common SNS Message Types
+
+### 1. SubscriptionConfirmation
+First message when you create the subscription. API auto-confirms by calling SubscribeURL.
+
+### 2. Notification (Bounce)
+```json
+{
+  "Type": "Notification",
+  "Message": "{\"notificationType\":\"Bounce\",\"bounce\":{...}}"
+}
+```
+
+### 3. Notification (Complaint)
+```json
+{
+  "Type": "Notification",
+  "Message": "{\"notificationType\":\"Complaint\",\"complaint\":{...}}"
+}
+```
+
+## Next Steps
+
+1. **Monitor logs while SNS sends**: `sudo docker compose logs api -f`
+2. **Trigger a real bounce**: Send to `bounce@simulator.amazonses.com`
+3. **Check the detailed logs** to see exactly what SNS is sending
+4. **Verify database updates** to confirm bounces are being recorded
+
+## If You Still See Errors
+
+The enhanced logging will now show you:
+- What headers SNS is sending
+- What body content is arriving (or if it's empty)
+- Where in the processing pipeline the error occurs
+- Full stack traces for any exceptions
+
+Copy the relevant log section and we can diagnose the exact issue!

 REST API for managing mailing lists and members with token-based authentication.
 
+## Overview
+
+This FastAPI-based REST API provides programmatic access to the mailing list system. It's designed for:
+- **Automation**: Scripts and integrations that need to manage lists/members
+- **Web Interface**: Powers the frontend at http://localhost:3000
+- **Third-party Apps**: Any application that needs mailing list management
+
+**For most users**, the web interface (http://localhost:3000) is more convenient. Use this API when you need programmatic access or automation.

 ## Managing Lists and Members
 
-### Via MySQL Client
+### Via Web Interface (Easiest)
+
+1. Open http://localhost:3000 in your browser
+2. Enter your API_TOKEN (from .env file)
+3. Use the tabs to:
+   - **Lists Tab**: View, create, edit, delete mailing lists
+   - **Members Tab**: View, add, edit, remove members
+   - **Subscriptions**: Click "Subscriptions" button on any member to toggle their list memberships
+
+### Via REST API (For Automation)
+
+See `api/README.md` for complete API documentation, or visit http://localhost:8000/docs for interactive docs.
+
+Quick examples:
+```bash
+# Get all lists
+curl -H "Authorization: Bearer $API_TOKEN" http://localhost:8000/lists
+
+# Create member
+curl -X POST http://localhost:8000/members \
+  -H "Authorization: Bearer $API_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"name":"John Doe","email":"john@example.com","active":true}'
+
+# Subscribe to list
+curl -X POST http://localhost:8000/subscriptions \
+  -H "Authorization: Bearer $API_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"list_email":"community@lists.sasalliance.org","member_email":"john@example.com"}'

 ## Usage
 
-### Development
+### Accessing the Interface
-1. Ensure the API is running on port 8000
-2. Open `index.html` in a web browser
-3. Enter your API token to authenticate
-4. Start managing your mailing lists!
-
-### Production (Docker)
-The web frontend is served using Nginx and included in the Docker Compose setup.
 
+**Via Docker (Recommended):**
 ```bash
-# Build and start all services
+# Ensure all services are running
-docker-compose up --build
+sudo docker-compose up -d
 
 # Access the web interface
 open http://localhost:3000
 ```
 
+**For Development:**
+You can also open `index.html` directly in a browser, but the API must be running on port 8000.
+
+### Getting Started
+
+1. **Authenticate**: Enter your API_TOKEN (from `.env` file) when prompted
+2. **Manage Lists**: Click the "Lists" tab to view and manage mailing lists
+3. **Manage Members**: Click the "Members" tab to add and edit member information
+4. **Manage Subscriptions**: Click "Subscriptions" button on any member to toggle their list memberships
+
+The interface saves your token in browser storage, so you won't need to re-enter it on subsequent visits.

 ### Subscription Management (New & Improved!)
 
 #### Member-Centric Subscription Management
-The subscription management has been completely overhauled for a much better user experience:
+The subscription management has been completely redesigned for the best user experience:
 
-1. **Access Member Subscriptions**: In the Members tab, click the "Subscriptions" button next to any member
+**How to Use:**
-2. **Visual Toggle Interface**: See all available mailing lists with modern toggle switches
+1. Navigate to the **Members** tab
-3. **Intuitive Controls**: 
+2. Find the member you want to manage
-   - Green toggle = Member is subscribed
+3. Click the **"Subscriptions"** button next to their name
-   - Gray toggle = Member is not subscribed
+4. A modal appears showing all available mailing lists with toggle switches
-   - Click anywhere on a list item to toggle subscription
-4. **Batch Operations**: Make multiple changes and save them all at once
-5. **Real-time Feedback**: The save button shows how many changes you've made
 
-#### Benefits Over Previous System
+**Visual Interface:**
-- ✅ **Much faster** - No need to add subscriptions one by one
+- **Green toggle** = Member is subscribed to this list
+- **Gray toggle** = Member is not subscribed to this list
+- **Click anywhere** on a list item to toggle subscription on/off
+
+**Batch Operations:**
+- Make multiple changes (subscribe to some lists, unsubscribe from others)
+- The "Save Changes" button shows how many changes you've made (e.g., "Save 3 Changes")
+- All changes are saved together when you click "Save Changes"
+- Click "Cancel" to discard all changes
+
+**Benefits:**
+- ✅ **Fast** - Toggle multiple subscriptions at once
 - ✅ **Visual** - See all subscriptions at a glance with color coding
-- ✅ **Intuitive** - Toggle switches work like modern mobile apps
+- ✅ **Intuitive** - Works like modern mobile app switches
-- ✅ **Batch operations** - Change multiple subscriptions simultaneously
+- ✅ **Smart** - Only saves actual changes, not unchanged items
-- ✅ **Less error-prone** - Clear visual feedback prevents mistakes
+- ✅ **Clear** - Shows exactly how many changes you're about to save
-- ✅ **Change tracking** - Only saves actual changes, not unchanged items
+
+#### Alternative: Legacy Bulk Subscription
+For power users who prefer the old approach:
+1. Go to the **Subscriptions** tab
+2. Select list and member from dropdowns
+3. Click "Add Subscription"
+
+This is still available but the member-centric approach is much more efficient for managing multiple subscriptions.
