As I’m always looking for a product that can compare ms exchange I found a nice post in my rss reader. It talked about the Zarafa product. It’s not opensource but at least it runs on Linux. The company behind is also contributing to openmapi .
I think I’m gonna test the development version. Maybe you can even use the exchange sync feature many phones have these days. At the moment I have a blackberry I like the fact that all my mail gets send on my device, but I miss the feature that my contact,tasks,… are synced
Anybody have any experience with this product ?
