## What it is
Mail-Archiver is a self-hosted web application for archiving, searching, and exporting emails from multiple accounts (IMAP, Microsoft 365, and personal Microsoft accounts). It offers scheduled folder sync, attachment support, mailbox migration, a statistics dashboard, multi-user permissions, OIDC authentication, a read-only REST API, and an MCP server for AI agent access.

## Use cases
- archive emails from multiple imap accounts automatically
- search archived emails with filters and attachments
- export emails as mbox or eml files
- migrate mailboxes between providers
- let ai agents search my email archive via mcp
- self-host an email backup solution with docker
- monitor email storage and sync statistics on a dashboard

## When to choose
- you need a self-hosted, multi-account email archive with scheduled syncing
- you want searchable long-term email storage with attachment support and export to mbox/eml
- you need mailbox migration between IMAP or Microsoft 365 accounts
- you want programmatic or AI-agent read access to archived mail via REST API or MCP

## When to avoid
- you need a full mail server or to send/receive mail, not just archive it
- you need a lightweight CLI tool rather than a web application with a database
- you require E2E-encrypted email storage, which it does not provide
