YunoHost is a Debian-based distribution that simplifies server administration to democratise self-hosting, while staying reliable, secure, ethical and lightweight. It can be installed on many kinds of hardware, from an old laptop to a VPS.

A YunoHost server includes its own mail server, and it lets you choose the webmail that goes on top of it. Cypht is one of those choices, and the one to pick if you want a single interface over several mailboxes rather than one account at a time.

1. No server yet? Start with the YunoHost install guide.
2. From the admin dashboard, open Applications.
3. Click Install and search for cypht.
4. Select the Cypht app.
5. Fill the form, or keep the defaults, and make sure the chosen URL is not already used by another app.
6. Wait for the installation to finish, then use open the app.
7. Log in with the credentials you provided during the installation and start declaring your email accounts.

The same installation can be done over SSH: The catalogue page lists the packaged version and its maintenance status: apps.yunohost.org/app/cypht.

• Cypht does not replace your YunoHost mailboxes: it reads them over IMAP and can add external accounts next to them.
• Since the package is community maintained, report installation problems to the package repository and Cypht bugs to the Cypht issue tracker.
• A step-by-step version of this procedure is also available in the installation guide.
