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?"

Real life reviews / experiences would be helpful

Our new CTO is making noises about us possibly ditching sendmail/linux and moving to Exchange. I'd really like to hear opinions about alternatives. He swears his mind is not made up already!

Can these open-sourced alternatives be a reasonable solution?

Don't know about OSS, but to avoid Exchange, find out all serious competitors, OSS or not, search for facts about them, and tell your CTO to analyze them closely and carefully. Try to stress him as much as possible that as you currently do not have any groupware (assuming this as you only mentioned Sendmail), the cost moving to Exchange would include mostly licensing and HW costs -- but, if you ever want to move off from Exchange, it will be very expensive, as Exchange's data format is neither open nor standards-based.

Try to convince him that whatever your solution will be, it's source code must either be available for competitors, or there must be an otherwise standardised way to convert data off if necessary. Otherwise you will just have yet another MS Office-like situation, where you're firmly locked into a single vendor and are forced to pay whatever MS wants you to pay -- even if the competitors' products would be able to handle your basic documents, you'd still have to rewrite all your existing VBA stuff (for example), causing huge migration costs.

In short: one of your primary criterias when choosing software vendors should be making sure, that you're never migrating to something, from which you can't cheaply and easily enough migrate off later, if that would ever became necessary. Try to make this fact clear for him and forget all unnecessary OSS advocating, and you're much more likely not to end up being an Exchange administrator.

Of course, if that CTO of yours is a PHB and already lured by MS marketing sirens, he'll probably not listen anyway... but then, that's life.
