Disclaimer: we are just migrating from Exchange to Google Apps.
Exchange is in no way perfect, and I am happy to see get rid of it. But if you want to / need to run your own service, none of the other solutions listed here come close.
Quoting Churchill:
"Indeed, it has been said that democracy is the worst form of government except all those other forms that have been tried from time to time."
Just replace Democracy with MS Exchange.
