Are you the target audience for this blog post, though? As far as I can tell, the post talks about one-user setups.

I'd argue that the starting point in a corporate environment, where you can assume that users can be quite negligent, is fundamentally different from a one-user setup, especially since I agree that you can't "fix" the user in corporate.

You want the e-mails gone, not just a warning about it, but a warning is perfectly fine if you're one person and have an idea what you're doing.
