I have recently had a couple of clients ask me about setting up a hosted Microsoft Exchange Server solution for them, that operates on servers based in Australia.
While I was looking into this, I noted that there were already some existing businesses that provided such services, and I found myself wondering if it was possible to do something like this myself and host my clients email on locally based cloud servers.
I had a look at Amazon EC2 and there is some documentation there, but I haven't been able to find out how, or if it is feasible, to set up an EC2 Exchange Server that can host email from multiple domains.
I have only just started looking into this, but would appreciate any advice on how to go about setting up a multi-tenant MS Exchange server on EC2?
Do you know of any links to pages with more info?
