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.
----------------- I aggree with using Lotus also except but one thing cost per user. How is it cheaper? I come up with anywhere from $15.00 - $18.00 per user. Albut running on Linux it would be cheaper (no CALs to buy). The other bad thing is the same as Exchange "The Lock In". A plus also to single sign on capabilities.
I hear migration from Lotus Domino to Exchange is cheaper. I do not have a validation on that either. Allbut migrating from Exchange 5.5 and 2000 is a pretty large ROI after complete migration. You pretty much don't need the extra support applications that's required for backup and retention.
