I would have thought that this was a small install:) We probably have at the most around 200-250. I was just guessing for growth. We too opt open source. Is zimbra a resource hog? Meaning do you think it would work with maybe a xeon quadcore with 4gb RAM?
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.

So are you required to run zimbras release of these packages?
If you are forced to use them then how delayed are the releases. Are you able to use something other than amavis and clam for scanning?? We use a product called VAMS released by central command for spam and antivirus on our mail server currently. These guys are very generous with pricing when it comes to educational facilities in case anyone is looking.
