#11 Add support for Exchange servers

[Amir Caspi]

It would be great if there were support for biff'ing of Exchange mailboxes. Not all Exchange admins turn on IMAP support, or they may make it more difficult to access (my sysadmin hides IMAP behind a firewall, for example, while the Exchange protocol is visible to the outside world), so being able to directly biff the Exchange server (rather than going through IMAP) would be great.

Not entirely sure how easy this is since Exchange is proprietary, but hopefully there are some open-source APIs for this that you can tie into.
