What you give up vs Gmail / Google Workspace

  • No admin web UI — all config is via files and the CLI
  • No bundled webmail or groupware (calendar/contacts)
  • Deliverability, DNS, and TLS setup are entirely your responsibility
  • Not a newsletter/marketing tool — mailboxes only

What you gain

  • • Full data ownership — self-host docker-mailserver 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 (MIT).
