## What it is
OpenArchiver is an open-source, self-hosted platform for legally compliant email archiving and eDiscovery. It ingests email from Google Workspace, Microsoft 365, IMAP servers, PST files, and .eml/Mbox archives, storing them in a searchable, deduplicated, tamper-proof archive.

## Use cases
- archive all company email from Google Workspace and Microsoft 365 into a self-hosted repository
- import legacy PST and Mbox files into a searchable email archive
- run full-text search across emails and attachments for eDiscovery
- retain business communications to meet GDPR or GoBD compliance requirements
- avoid vendor lock-in by keeping a permanent .eml-format mail record on my own infrastructure
- give auditors limited read-only access to archived mailboxes
- back up IMAP inboxes with deduplication and compression

## When to choose
- you need a self-hosted, sovereign email archive free from vendor lock-in
- you must ingest from multiple sources like IMAP, Microsoft 365, Google Workspace, PST, or Mbox
- you need fast full-text search over emails and attachments for eDiscovery
- you want an open-source (AGPL-3.0) alternative to commercial archiving products
- you want pluggable storage backends including local filesystem and S3-compatible object storage

## When to avoid
- you need real-time journaling, AES-256 encryption at rest, legal hold, or immutable audit trails, which are Enterprise Edition features
- you need SSO via OpenID Connect or SAML, which requires the paid edition
- you want a fully managed SaaS rather than self-hosting with Docker Compose
- you need archiving for non-email communication channels like chat or messaging platforms
