“These people” such as Hillary, Bush, Cheney, usually started off a mail service outside the Whitehouse to get their campaigns organised. Over time their entire entourage is using that mail server.

Then they get into Government and we expect them to transplant their entire support network into the new environment. That is not going to happen.

What is needed is for the mail server that someone starts up to support their campaign to be secure be default with Whitehouse-level security made easier than not using it at all.

The hard part is getting people to use S/MIME certificates so that messages are encrypted end to end and you never have to quarantine cleartext on your cloud service.

Surely there is an entrepreneur in the HN crowd ready to take this on?
