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
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.
