unoMail

unoMail is an open-source, self-hosted email platform built with Rust and React. It combines a complete mail server, modern webmail client, and administration panel in a single Docker container.

Designed for individuals, developers, and organizations, unoMail provides everything needed to host and manage email without relying on third-party providers or maintaining multiple separate services.

The platform supports SMTP, IMAP, POP3, and JMAP, alongside a modern webmail interface with threaded conversations, labels, advanced search, scheduled sending, snoozing, and multiple account support. Integrated calendars and contacts provide CalDAV and CardDAV compatibility.

unoMail also includes AI-powered features such as email summarization, translation, and suggested replies, with support for OpenAI-compatible providers, Anthropic, Gemini, and local models through Ollama.

Security features include two-factor authentication, passkeys, OpenPGP, S/MIME, and encrypted connections. Spam filtering and malware detection are handled through Rspamd and ClamAV integration.

A built-in administration panel allows administrators to manage domains, mailboxes, aliases, DNS records, TLS certificates, delivery queues, and server settings. Deployment is handled through Docker, with support for automatic certificates, backups, monitoring, and optional S3 storage.
