Rating and comments for Zimbra

Zimbra is absolutely the best, way better than Exchange. The webclient is lightyears ahead of exchange.

It is way faster, have nearly instant search and have antivirus/antispam build in.

Works perfectly with Outlook client and iPhone connector.

The OS version lacks a few features that would be nice-to-have, but I understand that VMWare needs to earn money somehow.
However, it's a great Email/Groupware solution, easy to install and administer, and works like a charm!
