The amount of QA needed to pull something like Zimbra off is staggering (sometimes it's still not enough QA....) My own mail is qmail-only - I gave-up trying to get all the calendaring-packages running long ago. But at work, we have Zimbra and is is really cool IMO. It has a slick web-interface, it sync's with Outlook, Mac - and then there is this great/horrible fat client called Zimbra Desktop... ;-) I have to admit, though, that the list-price for a small amount of mailboxes looks not so cheap (esp. if you want Zimbra Mobile). (How many mailboxes does the original author want to replace, actually?) But still, I'm kind of fascinated by it - mostly, because it's very openly developed and by browsing through their bugzilla and P4 repository-webinterface, you get a good idea of what current issues there are, what would get fixed by going to a newer version (and which new bugs to expect). I wish every vendor did that. We run it on CentOS, BTW (test/dev environment via Virtuozzo, production on physical hardware). Rainer
