Thank you. Your answer was very informative.
There have been no successful attacks, but I always think a "worst case scenario" sense. You are right, once root level access is gained there is little any other measures could achieve.
I have looked into GPG but I am not able to install software...
Hello,
I run a Postfix server with Courier and was wondering how I could encrypt my virtual mailboxes? My SMTP and IMAP traffic is already encrypted with TLS, but if root access was compromised anyone could read my mail.
What is the best way to encrypt the virtual mailboxes?
Thank you,
