Zimbra isn't too bad in terms of resources. We have it running on a system with several hundred users, primarily doing e-mail on a system with a single Intel(R) Pentium(R) D CPU 3.00GHz and 4GB RAM. My primary gripe with Zimbra is that it wants to take over a machine with its own versions of openldap, postfix, amavisd, clamav, etc., and these are not always kept current. We have one Zimbra system running as a VM under the free VMware server, allowing us to screen incoming and outgoing e-mail with current versions of amavisd and clamav before passing it to the VM for final delivery. Zimbra also works independently of the Linux user system, which some consider a feature, but I don't like as I like to be able to handle many things at the user's $HOME directory level. In particular we normally use courier-imap with Maildir storage, and our own server-side filtering and routing before delivery.
