I remember years ago when Mail-in-a-Box first started it was suggested to put it on a raspberry pi so that you can plug it in your computer and use it on the go. Your own portable email server that can go anywhere you can.
Now if I can remember correctly, it was also routing traffic through Tor.
Looking around the forum and install page I no longer see the instructions to make this portable and email routed thru tor.
Does anyone remember this? And, does anyone have the link to the instructions?
