What you give up vs Gmail / Google Workspace

  • Requires a dedicated Ubuntu VPS with a clean IP reputation; shared hosting is not supported
  • No built-in bulk mailing or newsletter campaign tools
  • Limited horizontal scalability; single-server architecture only
  • Webmail (Roundcube) is functional but far less polished than Gmail's UI

What you gain

  • • Full data ownership — self-host Mail-in-a-Box on your own infrastructure.
  • • No per-seat SaaS bill (Gmail / Google Workspace: per-mailbox fees and data privacy).
  • • Open-source code you can audit and extend (CC0-1.0).
