You have a good point. We just recently deployed an in-house mail server for a client with security concerns; they wanted all of their intra-office email to not leave the building. Our mail server does backup duty for their mail server, in case their connection drops or anything goes haywire, and we monitor their server and keep it healthy for a really low monthly amount. I had only sorta-kinda considered trying to offer that to a wider audience, but I didn't really think the market for it was that big. I might be wrong.
