>I use Zimbra OS Edition with more than 300 users, Ajax and HTML capable and very easy to setup. 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. I was hoping for Mobile support which it looks like the OS version of Zimbra doesn't have. Regardless, I should have been more clear in that I am not concerned about GPL compliancy but meant free when I said open source. Thanks for all the suggestions everyone! jlc _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
