Mailcow Alias Manager Autor: goacid

Mailcow Alias Manager lets you manage email aliases on your self-hosted Mailcow instance directly from your browser — no proxy, no backend, no third-party server.

Features

• List all your aliases at a glance
• Create, delete, and enable/disable aliases
• Search and filter aliases instantly
• Secure API key storage (browser's native encrypted storage)
• HTTPS enforced — your credentials never leave your own server
• Available in 13 languages: English, French, German, Spanish, Italian, Japanese, Korean, Dutch, Polish, Brazilian Portuguese, Russian, Turkish, Chinese (Simplified)

How it works

The extension connects directly to your Mailcow API using your personal API key. All requests go straight to your self-hosted instance — nothing is sent to any external service.

Setup

1. Click the extension icon and open Options
2. Enter your Mailcow URL (e.g. https://mail.yourdomain.com) and your API key
3. Click Test connection then Save

Your API key is generated in Mailcow under: Configuration → Access → API.

Privacy

This extension collects no data. It does not track, log, or transmit any information beyond the API calls you initiate to your own server.
