I would like to have an Exchange server to handle all internal email, but have all outside addresses relayed out to our host provider Hostway. I would also like for our external email to come into the exchange server and hit the appropriate mailbox. I mostly want to do this to be able to use the calendar and scheduling features of Outlook and Exchange. I already have copy of Exchange 5.5 and server that could run it, so the cost would not be great to set it all up. Can Exchange handle a scenerio like this and if so would it be too much of an administrative nightmare than it is worth?
