[Dovecot] E-Mail Encryption

[Patrick Domack]

The only benefit this would being, is email being saved on the server  
would be encrypted. Otherwise it offers no protection.

I guess if you paranoid that the system admin might read your emails,  
but then, he can just as easily read them as they come in or out of  
the system.
