Hello.
I'm an intern at a company and my boss want's me to check if it's possible to encrypt the emails while they're stored.
i know they can be encrypted during transit but if it's possible to prevent someone on the worng side of the firewall from snatching sensetive information.

-iRedMail version 0.9.9
-PGSQL
sadly i'm not able to get all the information to the questions at the top.
hope this is enough otherwise i'll attempt again with more information
