Just an FYI.... Novell Netmail was bought out by Messaging Architects a short while ago. If you're unfamiliar with it, Netmail was the scaled down version of GroupWise email, engineered to handle large number of accounts and large volumes of email with as little overhead as possible. It runs on Windows, Linux, and Novell servers, and supports multiple client protocols (IMAP, POP, etc) and includes a web interface that provides both email and calendaring. Anyway, since taking over development of the product from Novell, they have begun offering it free to educational institutions for student email accounts: http://www.messagingarchitects.com/en/industries/Education/FreeEmailForStudents.asp This is not a hosted solution, where your accounts are on their servers. This is the software for free, to run on whatever hardware you prefer in your own environment. You can download it for free to play around with, or seen an online demo from the links at the bottom of the page. Share and Enjoy.
