We have Zimbra running with several hundred mail users on a CentOS 4.5 system (it wouldn't run on CentOS 5 when we started the project). It works well, but does not play nicely with others, basically taking over major parts of the system, postfix, openldap, IMAP, etc., and does so in a manner that makes it difficult to integrate in some systems (e.g. put it behind a postfix, amavisd, clamav, spamassassin system that I can keep current with the Latest & Greatest updates, and configure DNSRBLs to my liking). I like to think I have better solutions for e-mail handling than Zimbra, and much prefer to use them unless there's an absolute demand for Exchange functionallity. I won't get into the licensing religious wars, nor do I mind paying for proprietary solutions if they do a better job for my paying customers than I can do with open source. The horde/imp/kronolith/... family of programs, provide good functionallity, but, like any webmail solution, have some basic limitations due to the web interface.
