SUSE Openexchange Under GPL
Gustavo writes "'Netline Internet Service announced today that it would contribute its OPEN-XCHANGE Server, the core technology underlying the industry's top-selling Linux-based groupware, collaboration, and messaging application, under the GNU General Public License (GPL).' How does it compare to OpenGroupware.org which was open sourced a year ago?"
Your experiences do not match mine.
There are plenty of huge, multi-national Exchange enterprises out there. Some have hundreds of thousands of users, and 5000 or more per server. They're not all having the same trouble with the product you claim to have experienced. Maybe you just don't know as much about Exchange as you think you do.
