My company is currently looking to bring out email and website in house. Our managers are looking for some costs and time benefits and so on and having never had the email and website in house. we have no prior data to compare. So I was wondering if anyone here could give me some ideas of cost of maintenance and additional work load. We are looking to put up a linux system. We have about 75 email accounts and approx. 50 employees. Let me know and thanks.
