## Description

OmniMail is a self-hosted webmail that runs entirely on Cloudflare's serverless platform. It uses Cloudflare Email Routing to receive mail for your domains, stores messages in D1 (SQLite) and R2 (object storage), and processes emails asynchronously via Queues. A single instance manages multiple domains, users, and mailboxes with a full permission model (super admin, admin, user, temporary). Optional sending is provided via Resend or SendFlare. It also aggregates external accounts: iCloud+ Hide My Email aliases, Gmail/Workspace via IMAP, Microsoft (Outlook/Hotmail/365) via OAuth2+IMAP, QQ Mail via authorization codes, NAVER and Yandex via app passwords. The UI is a React SPA with light/dark/system themes, responsive for desktop and mobile. A Chrome extension (OmniMail Float) and a native Android app connect to the same API. Deployment is Git-driven via Cloudflare Workers Builds — either a one-click deploy or a Fork for long-term updates. The project is MIT-licensed and currently at v1.3.0 (Web/API) with Android in preview (0.3.0).
