Looks professional in terms of interface. Good community too. The only problem is that it was bought by Yahoo which is planning to buy by M$, but since OS version was GPL, then I assume that the project will continue even after acquired by M$. Maybe. it is NOT GPL, it is YPL <http://www.zimbra.com/license/yahoo_public_license_1.0.html> and can not be redistributed without attribution ... so if the M$ buy out happens there is no guarantee that another version could be made under the terms of the YPL. There has been MUCH dismay about this in the Zimbra forums ... and we will have to see what happens if the buyout happens. http://www.zimbra.com/forums/zimbra-success-stories/14964-ms-offering-buy-yahoo.html So, I like zimbra as an exchange replacement, but I would not recommend it for NEW installs. This is another example of how the license "DOES MATTER". But then again, I am a GPL "kool-aid" drinker, so take my opinion with a grain of salt. -------------- next part -------------- A non-text attachment was scrubbed...
