So, I too just got a Droid and am being met with mixed success as far as it talking to our corporate Zimbra server. Partial emails and no "click here to download rest of message" functionality, etc.. But, overall it's working pretty well, I get emails rapidly, I can send/reply, view calendar entries, etc..

Anyway, just wanted to add to this conversation, since it didn't appear to have been mentioned previously. Calendar event creation. If I setup a new one on the phone it is on my calendar immediately and looks to be correct. Invites to other participants however result in a null email which the Zimbra web client recognizes as a calendar-related email but there is no accept/decline buttons present.

Part of the headers of one of the invitation emails:

Message-Id: <cm65ar5m2ba3e36uoq2u597k.1258051984395@email.moto rola.com>
Content-Type: text/calendar; charset=utf-8; method=REQUEST
Content-Transfer-Encoding: base64
MIME-Version: 1.0
X-Mailer: Zimbra 6.0.2_GA_1912.RHEL5_64 (MobileSync - Moto-Android/0.1)

What follows that is about 20 lines of Base64 encoded text.

Oh and as an interesting aside, I've looked at headers of a few emails from the phone and it appears the Message-ID: references email.motorola.com on calendar generated ones and email.android.com on just regular emails.
