The most limiting device is probably the Android phone.

Most can usually handle syncing with Google or Microsoft ActiveSync
(part of Exchange). There is an ActiveSync server for Linux called
"Z-Push", which we use a work.

It can handle multiple backends, such as LDAP for contacts, CalDAV for
calendars, IMAP for email, etc. Then for the servers on Linux we use
OpenLDAP for LDAP, and Davical for CalvDAV.

The main problem has been with people inboxes of about 10,000+ emails,
where it can become a memory hug (over an 100MB of RAM per person).
Of course, the other problem is that it is written in PHP.

It's part of the Zarafa system, but is open source and can be run on
it's own:
