Seconded. In terms of functionality and interface, I like Zimbra a lot, but they make Microsoft and Apple look like amateurs in the "our way, or not all" game. As a small friends-and-family installation, I can't afford to dedicate a whole box exclusively to Zimbra[0], and trying to make it play nice with anything else running on the same server is a pain. As you say, pretty much anything that they don't have a GUI setting for is a nightmare to keep working across upgrades. I'd imagine it's actually better if you're planning a bigger-scale deployment and can have the architecture a lot more in line with how they expect it to be from the start. Regards, Tim. [0] OK, I probably could now with a VM, but the virtualisation support on my hosting box wasn't really there when I started...
