What is the best way to secure an email account so that even the systems administrator cannot read a user's email?
Here is the scenario I am facing:
I am the site administrator for a domain that is hosted in a shared Linux / Apache / Cpanel environment managed by site5.com. One of the email accounts for the domain I manage is used to send / receive confidential information that even I should not have access to. Since I am the site administrator, I have full access to the system, so I can get in and view the files used to store the email messages. Basically, I have the ability to snoop on other users if I want to.
Is there any way that this sensitive email account can be secured so that even I cannot view the emails if I desire?
