This white paper answers three fundamental questions for
Internet service providers (ISPs) who want to use Exchange 2000 to provide
consumer messaging services based on Internet protocols such as Simple Mail
Transfer Protocol (SMTP), Post Office Protocol 3 (POP3), Internet Message
Access Protocol 4 (IMAP4), and HTTP:
- How many users can be supported on a single Exchange 2000
server?
- How many servers�including directory servers, front-end
protocol servers, and so on�are required to support
x number of users?
- How should the servers be configured in terms of RAM, disk,
and processors?
