hmmm. maybe if you configure email server. I did postix/cyrus/apache.
BES is using MS Exchange for email. Enterprise server provides backbone, for service. It is used to synchronize data between email server (e.g. MS Exchange) and BlackBerry wireless devices.
BES provides administrators with the ability to connect pre-defined performance data.
BES allows centralized management of AD, SQL, cytrix, IIS, DNS and more. Well it is a little more complicated than email.
I don't see any point of arguing.
To understand to some extent what BES does simply read BlackBerry - BlackBerry Enterprise Server for Microsoft Exchange
MS Exchange provides email services, for web interface, you need IIS (to keep with MS). All groupware structure is provided by MS Exchange (calendar, contacts scheduling).
For email client to see HTML content (available already) no server config is required.
Simply put BES (alone) will not be able to provide email.
