The future of email is JMAP, which is supported by Cyrus IMAP and Cypht
Why not Roundcube
Why not Kolab
- Kolab is a great standalone mail stack suite. Kolab was the mail stack component in WikiSuite for the first few years, but it was too much work to integrate tightly and thus, it stayed quite standalone from the rest of WikiSuite. So we moved to a more tightly integrated solution.
- Kolab uses Roundcube, which doesn't support JMAP
Why not Apache James
- Apache James supports JMAP so it could have worked, but it would be too much work to integrate nicely with ClearOS
