Secret Handling

As a self-hosted admin web app, security depends heavily on deployment: TLS termination, restricting admin access, secure session/cookie settings, and protecting the database. Scope/least-privilege for API access is not evident (likely coarse admin-level access). Dependency hygiene and secret-handling quality can’t be verified from the provided prompt.

Best When

You want a self-hosted, database-backed web UI to administer a virtual-mail Postfix/Dovecot setup.

Avoid When

You cannot securely expose/administer a web application (TLS, hardened hosting, restricted access) or you need an agent-friendly programmatic API surface rather than a web admin tool.

Use Cases

• Provisioning and managing virtual email domains and mailboxes
• Administering aliases and mailbox routing rules
• Database-driven configuration of Postfix/Dovecot virtual users
• Centralized web UI for email administration tasks

Not For

• Replacing mail transfer agents or mail delivery components (Postfix/Dovecot are still required)
• Highly dynamic tenant provisioning at high API-call volume without careful engineering
• Use where a browser-based admin UI is not acceptable for security/compliance reasons

Authentication

Methods: web session cookies (typical for admin panels) database-backed admin users (typical for postfixadmin deployments)

OAuth: No Scopes: No

No OAuth/API-scope model described in the provided prompt; authentication appears oriented around web UI/admin access rather than API tokens.

Pricing

Free tier: No

Requires CC: No

Self-hosted open-source project; hosting and operational costs apply.

Retry Guidance

Not documented

Known Gotchas

⚠ Primarily a web admin interface; programmatic agent integration (CRUD) is not standardized via REST/OpenAPI.
⚠ Operational changes (email admin actions) can be stateful and have security implications; avoid blind retries without understanding database side effects.
⚠ Authentication is likely session-based; agents may need cookie/session handling rather than simple API keys.

Alternatives
