Creating Aliases

AnonAddy supports multiple alias formats:

2. UUID Aliases: 94960540-f914-42e0-9c50-6fecbe7f5061@yourdomain.com
3. Custom Aliases: newsletter@yourdomain.com

Replying Anonymously

Reply to forwarded emails directly. AnonAddy will send the reply through the alias, maintaining your anonymity.

Encryption

Enable GPG encryption in Settings to encrypt all incoming emails with your public key.

Architecture

Services

The package runs multiple services via supervisor:

• NGINX - Web server (port 8000)
• PHP-FPM - PHP processor
• Laravel Queue Worker - Background job processing
• Laravel Scheduler - Cron job handler
• Postfix - SMTP server (port 25)
• Rspamd - Spam filtering (port 11334)

Data Persistence

All persistent data is stored in /app/data:

• /app/data/storage - Laravel storage (logs, cache, sessions)
• /app/data/dkim - DKIM keys
• /app/data/postfix - Postfix spool
• /app/data/rspamd - Rspamd data
• /app/data/app_key - Laravel application key
• /app/data/anonaddy_secret - AnonAddy secret for anonymous replies

Database

The package uses:

• MySQL - Main database (via Cloudron addon)
• Redis - Cache and queue backend (via Cloudron addon)

Email Integration

• Inbound: Postfix receives emails on port 25
• Outbound: Cloudron SMTP addon for sending emails
• Spam Filtering: Rspamd filters incoming emails
• Virtual Aliases: Postfix queries Rspamd for alias lookups

Troubleshooting

View Logs

cloudron logs --app anonaddy.yourdomain.com -f

Shell Access

cloudron exec --app anonaddy.yourdomain.com

Common Issues

Emails Not Receiving

1. Check MX records: dig MX yourdomain.com
2. Verify port 25 is open on your Cloudron server
3. Check Postfix logs: cloudron logs --app anonaddy.yourdomain.com | grep postfix
4. Test SMTP: telnet anonaddy.yourdomain.com 25

Emails Marked as Spam

1. Ensure SPF record is configured
2. Add DKIM keys in Settings
3. Configure DMARC record
4. Check your server's IP reputation

Queue Not Processing

1. Check Laravel queue worker: cloudron logs --app anonaddy.yourdomain.com | grep queue
2. Verify Redis connection
3. Restart the app: cloudron restart --app anonaddy.yourdomain.com

Application Errors

1. Check storage permissions in /app/data/storage
2. Clear cache: cloudron exec --app anonaddy.yourdomain.com 'php artisan cache:clear'
3. Run migrations: cloudron exec --app anonaddy.yourdomain.com 'php artisan migrate'

Database Migrations

Migrations run automatically on startup. To manually run migrations:

cloudron exec --app anonaddy.yourdomain.com
cd /app/code
php artisan migrate

Clear Cache

cloudron exec --app anonaddy.yourdomain.com
cd /app/code
php artisan cache:clear
php artisan config:clear
php artisan view:clear

Updating

To update to a new version:

1. Build the new version with updated tag
2. Uninstall the old version: cloudron uninstall --app anonaddy.yourdomain.com
3. Install the new version: cloudron install --location anonaddy.yourdomain.com --image andreasdueren/anonaddy-cloudron:NEW_VERSION

Note: Always backup your data before updating!

Development

Local Testing

1. Clone the repository
2. Make changes to configuration files
3. Build locally: cloudron build --tag test
4. Install for testing: cloudron install --location test.anonaddy.local --image andreasdueren/anonaddy-cloudron:test

File Locations

• Application code: /app/code
• Persistent data: /app/data

• Supervisor config: /etc/supervisor/conf.d/anonaddy.conf

Security Considerations

1. Change Default Password: Immediately after installation
2. HTTPS Only: Cloudron automatically provides SSL/TLS
3. SPF/DKIM/DMARC: Configure all email authentication records
4. Firewall: Ensure only necessary ports (80, 443, 25) are open
5. Updates: Keep AnonAddy updated to latest version
