Article = India will be requiring its governmental employees to store governmental e-mails on governmental e-mail systems.
Seriously with that headline?
On the other hand, at least here in GA I've noticed that many small businesses have stopped self-hosting email, if they ever did to begin with, because it was cheaper to contract it out. They could get greater reliability for a reduced cost compared to having (potentially) additional IT staff to handle the workload associated with it (same with other hosting services). Or if they were too cheap to hire the additional staff, as one company I saw was, the IT staff convinced them to outsource it so they could free up their time to work on things the company actually needed them to focus on.
Why? Because our incompetent IT director won't allow access to the email server if it's not through a VPN. What is this, 2001?
