I am an open source person but when it comes to something like that I hate to say it but Exchange has it covered. What's others opinions? How would you do it? I'm currious to know how you would do this in an environment that has many compliance problems. Mainly issues of privacy rights not being violated.
For a commercial solution, Lotus Domino might be even better. It is cross platform (runs on linux), supports all those same standards for various business standards and audit policies, you get a good web-client, pop and imap in addition to the Notes client (on Windows and Linux only).
Also, it is cheaper than Exchange.
