What Piler actually does
Piler is an open-source email archiving solution designed to store and index large volumes of electronic mail. It provides a centralised repository for organisational email data, supporting long-term preservation and retrieval within the Archiving and Digital Preservation category.
Best fit: It suits system administrators who need a self-hosted mail archiving system under a GPL-3.0 licence to meet compliance or data retention requirements.
Worth knowing: Development activity is currently slowing, meaning you should evaluate whether the maintenance health matches your long-term operational needs.
Deployment notes
As a compiled application built with C and distributed via Docker or deb packages, it typically requires persistent storage volumes for mail data and an external database backend.
