Modoboa is an open source mail hosting and management platform that helps you deploy and operate a full email server through a modern web interface. It integrates common mail components (MTA/IMAP, filtering, reputation and policy features) around a central SQL database.

Key Features

  • Web-based administration panel for domains, mailboxes, and aliases
  • Integrated webmail with a simplified user interface
  • Calendar and address book features
  • Per-user mail filtering with Sieve and auto-reply messages
  • Reputation and deliverability tooling including DNSBL checks and DMARC reporting
  • Optional integrations for content filtering/quarantine workflows (for example via Amavis)
  • Email traffic statistics and reporting dashboards
  • Modular architecture via extensions for adding functionality

Use Cases

  • Hosting email for a small business or organization with multiple domains and users
  • Replacing third-party email providers while keeping a webmail-based workflow
  • Providing managed mail services with admin and migration tooling

Modoboa is a practical choice for teams that want a unified UI to deploy, configure, and manage a standards-based mail stack while keeping control over data and policies.
