I need cheap hosting controller for windows 2000 server, include email management. Ensim is good but too expensive for me!. Any idea?

I think the best you are going to do is Ensim @ $99.99.

Ensim $99? where? I saw on their website (www.ensim.com) cheapest cost = US $179 for 5 domains only!.. I need 100 domains!
And also I need email manager for my Win server, include my user can manage their email self, where?

For ensim win2k also you will need to buy the mailmax software for mail use, which is $500
