Zentyal & Blackberry

[JPB]

I have had many problems with Blackberry and there days other PDA type phones.  The network provider remove or disable the pop3/imap4/smtp functions from the Blackberry connection by default and then blackmail the user to pay extra to re-gain the functionality.  Although this is unacceptable in general terms as it infringe on the "freedom" that exist on the internet, we need to live with it. (my Apologies, I had to get this off my chest)

The problem is that by default the providers allow connectivity to MS Exchange server in a Domain.

Is it possible for me to configure the Zentyal / postfix / Groupware (Zarafa) to allow direct MS Exchange connectivity from the Blackberry?

According to Zarafa, their professional version supports Blackberry.
You can see their prices here: http://www.zarafa.com/content/prices and their editions here: http://www.zarafa.com/content/editions.
It's about 28 EUR/user, for a minimum of 20 users (ie 560 EUR).

Don't know why the Professional version is cheaper than their Standard one ...
