I have a client request on setting up mail services in her company, she requested to have all the emails filtered manually by one administrator before distribute out to the respective email accounts.

She only need less than 20 email accounts to be setup. I first thought of getting a hosting package that provide 25 POP3 accounts and have them forwarded to one account but no, its not a good idea.

She has already install a Win2000 server at her office for accounting purposes and have no internet connection yet. We are to suggest the solution to her with only this requirements.

Anyone have any solution to this ?
