From everything I've read, the company does. Work email is NOT private, and there is no expectation of privacy. I think there have been court cases about this? As I understand it, the employer has every legal right to read, filter, whatever, any email going into or out of their email servers.

Encryption? I'd think they could subpoena the employee to reveal the key?

Hypothetically speaking, someone made a very, very big mistake.
