What is it?

Eonvelope is a self-hosted email archive that keeps copies of your emails over the long term. It automatically and continuously fetches messages from mail accounts using IMAP, POP, Exchange or JMAP, so the archive stays up to date without manual exports.

Archived emails, attachments and correspondents can be filtered and searched through a Bootstrap 5 web app with PWA support. Emails can be imported and exported in several formats, related emails are identified, and messages can be restored to a mail account. The project also integrates with other self-hosted tools such as Paperless-ngx, SearXNG and Grafana.

The application is deployed as a container image, with example setups for Docker, Podman and Kubernetes. It includes a full API, SSL certificate support out of the box, and a slim mode for low-spec systems.
