First I'd like to say that I've been tracking Zimbra for what must be well over a year. We run an almost excusively Debian based server environment, with one straggling Exchange server left, which we'd like to replace.
We've been waiting for Zimbra to support 'shared folders' (or an equivalent) as we heavily use them accross the company, and 4.0 has them! (caused a small dance in the office I must say).
Any sign of a Debian Network Edition? We need all the features of the Professional Network Edition, and would be a nussaince to have to find a spare box to (buy first and...) install RHEL (not a SuSE fan ) on just for zimbra.
