So the NSA is spying not only on my Facebook account, but also reading my mail? Shame on them! Until recently, I was not overly anxious of my private mails getting into the wrong hands, but things change, don’t they?
I have my own postfix server up and running, which hosts about 10 mail addresses, mostly of Longboarding Ulm members. I implemented data security ‘at transport’ (i.e. TLS and related stuff), but I didn’t care too much about data security ‘at rest’, namely encryption on disk.
