What is Eonvelope?

Eonvelope is an open-source self-hosted email archive built with Django that preserves emails from multiple accounts using IMAP, POP, Microsoft Exchange, and JMAP protocols. It automatically fetches and archives emails continuously, identifies related emails and conversations, and supports importing/exporting in various formats. The web interface is mobile-friendly with PWA support. It integrates with Paperless-ngx for document archival, Immich for photos/videos, Nextcloud for contacts, and Searxng for search. It also supports OIDC authentication via Keycloak, Authelia, or Authentik, and exports Prometheus metrics. Deployment is via Docker Compose, Podman, or Kubernetes with a MariaDB database (PostgreSQL and SQLite also supported). A slim mode reduces resource usage for low-spec systems. Licensed under AGPL-3.0.
