| Purpose | Cyrus IMAP is an email, contacts, and calendar server. | Mail-in-a-Box turns a fresh cloud computer into a mail server that lets users run their own email service. |
| Security | The feature documentation lists Kerberos, LDAP, and SQL authentication, access control, and a sealed system design. | The control panel supports TOTP-based two-factor authentication, and the security guide says credentials are sent through SSH/TLS rather than in the clear. |
| Support | The project points users to active mailing lists for help. | The project directs users to its discussion forum, GitHub issues, and Slack chat for help. |
