MS Exchange Server Replacement / Top10
I guess that a lot of you out there are using Worgroup Software that runs on Linux.
I would like to create a Top10 of Workgroup-Software(preferably OpenSource)
and then make a poll which is the community's favourite.
The software hast to run on linux and needs to have a Web Interface (and optional connectivity to Outlook or other Clients).
Which Exchange Server Replacement is your favourite?
