AnonAddy (addy.io) is a self-hosted anonymous email forwarding service built with Laravel, Inertia.js, and Vue 3. In production, it allows users to create email aliases that forward to real inboxes, with support for custom domains, PGP/MIME encryption, user-defined rules (sender/subject/header conditions with actions like block, quarantine, label), and a blocklist. The system receives inbound email via a Postfix pipe, applies rules, and either forwards, replies, or sends-from aliases with rewritten headers, List-Unsubscribe banners, and optional DKIM signing. Outbound sending handles VERP bounce tracking and stores failed deliveries with deduplication. The architecture is a monolith Laravel application with a REST JSON API (used by mobile/extension clients) and a server-driven SPA frontend. Key entry points include the ReceiveEmail console command, the CustomMailer driver, and numerous API controllers under /api/v1/. The frontend uses reusable Vue components and Inertia form handling across pages for alias, recipient, domain, rule, blocklist, and settings management.
