We have SBS 2008, which is configured to send/receive our outsidedomain.com email directly. However, how do we setup an email only account to allow a program that sits outside our network to send mail from outsidedomain.com? In other words, in the previous setup of our email being hosted by a 3rd party, we would simply add a pop account email@example.com and we could have any machine anywhere in the world, configured to send/recieve mail.
With SBS, our current email accounts are tied to internal domain accounts, but I dont want to create internal domain accounts (counts against our CALs, right?) for a simple email only user that needs zero internal network access.
