Hi-- I have a client who wants large-scale email hosting, naturally at a low price. I was thinking either Google Apps or a hosted Zimbra system. I've used both, but never used Zimbra in a real "production" environment. I'm gonna use a hosted service, so I'm not too worried about the server admin aspect, but I'm hoping some of you might have some input on how it stacks up against a MS Exchange system and the Google Apps I mentioned from an end-user's view.
Thanks
