You'd require an email server with Exchange (several other email systems are also supported by Blackberry), another server with Blackberry Enterprise Server (BES) installed, high speed or dedication internet connection, a quality Uniterruptable Power Supply (UPS) capable of supporting at least two servers, your own domain name, etc.
A good setup would include redundant hardware and internet connection for proper fail-over.
IMO, you'd be better off just paying for hosting.
