Add support for Zimbra
It was part of an integration project in 2014 on the wiki.
Zimbra is a groupware and email server that has a free software edition among others. It offers email, calendar and address book via IMAP/POP3/SMTP, CalDAV and CardDAV, apart from offering a web UI that can be accessed using a Web browser.
Prospective integration points would be Evolution, Evolution Data Server, Calendar and Contacts. We plan to offer IMAP/SMTP, CalDAV and CardDAV, but not POP3.
It is the first link on Google when searching for zimbra + gnome. It seems this project never reached an implementation since that. Would be great to support it though.
