Re: The difference is that folk should use TWO emails!
Actually for someone like Clinton you need four plus spam accounts.
1. Publicly disclosed official email account. This is the one maintained almost exclusively by staff. It gets bombarded by world plus dog.
2. Actual official email account that the Secretary uses to exchange email with other government officials. At that level, it should default to encrypted.
3. Private fundraising email account. At the Secretary level, you have to assume they are active in partisan activities including fundraising. It's illegal to use official accounts for partisan purposes. And you probably don't want this account mixing with your actual personal account.
4. Private personal account. The account for people who actually know you on a first name basis. Optional account for hot dates.
Is it a lot accounts? Yep. It's also the price of all the laws they passed governing how government works.
