Dan Feldman wrote One other question: This project will probably have to have an e-mail interface. I could implement an SMTP server in Python that interfaces with Zope, but it would be much simpler to have a web-page interface that connects to an IMAP back end. It would be easiest to validate users who log on against the IMAP server, so all the passwords stay consistent. How difficult would it be for me to create an IMAPUserFolder product, a bit like the NisUserFolder and the SmbUserFolder? Is this practical?

This already exists - Michel P. did it as part of his Notmail product. It's available in the CVS tree... Anthony -- Anthony Baxter <anthony@interlink.com.au> It's never too late to have a happy childhood.
