Cypht is a webmail client which supports JMAP (and IMAP of course) that was added to Tiki Wiki CMS Groupware version 20.x, and much improved in Tiki 21.x.
Cypht with Cyrus IMAP and http://sabre.io/ is the base of WikiSuite's mail stack. As of 2019-09, it is far less feature-complete than Kolab, but it is more tightly integrated. And over time, it will become feature-rich, as is the nature of Tiki's community and development model: Tiki is the Free / Libre / Open Source (FLOSS) Web application with the most built-in features. Please see https://dev.tiki.org/Email-as-a-first-class-citizen
Cypht has what you'd expect from a webmail client, and some very interesting features like aggregating email from multiple accounts.
