Ms Exchange vs dovecot

[Guido Goluke, MajorLabel]

I'm in the process of implementing Z-Push: a PHP-written layer that sits 
between your client and backends and offers activesync, since clients 
that belong to multinationals that offer propietary stuff (MS, Google) 
try to steer you around protocols like CardDAV, CalDAV and IMAP since 
their protocols are 'pushier' (while in reality the only 'push' they 
provide is in the direction of their products).

The only thing they *do* properly support is activesync. Z-Push lets you 
connect to Dovecot for IMAP/mail and to for instance nextcloud for 
CardDAV and CalDAV while offering *all* those protocols to clients, 
which means that Thunderbird, Outlook, Gmail and Apple devices all can 
get their optimal experience.

There are some issues regarding the IMAP flag synchronization which I'm 
working on (https://jira.z-hub.io/browse/ZP-1561). I also have some 
notes on implementing a multi-domain setup 
(https://forum.kopano.io/topic/3265/multiple-z-push-instances-on-one-server/6)

Guido Goluke
