Thank you for your response, Dave. A couple other questions...
1) there seems to be no SSL certificate on the sign up page (http://www.exchangemymail.com/order/order.aspx)
. I am a bit hesitant to put those numbers in. Is there an alternate, secure site?
2) on the sign up page, there seems to be no option that is appropriate for someone like myself who wants to use an existing email address (such as a yahoo account). Which option should be selected.
3) in what part of the country are the servers physically located?
