hmm. First define what "encrypted" means in this case, the whole partition
with one master key, encrypted for each user, ... . For the first, several
block device level approaches exist, for the latter check out AFS or
Encfs.
- SSL or TLS only for SMTP and IMAPS
Well, if you use an inspecting firewall, that checks the traffic, you will
be on the save side of life.
Does IMAPS means: no STARTTLS over IMAP? Then drop the imap listener in
Dovecot.
- Talking only to some known other same-secured servers
use an IP firewall.
