What you give up vs SendGrid
- 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 (SendGrid: per-email costs at scale).
- • Open-source code you can audit and extend (CC0-1.0).
