It was originally designed to run on the Beaglebone Black, but that should be regarded as the most minimal system, because it's single core and has by today's standards a small amount of memory. Obviously the more powerful the hardware is the faster things like web pages (blog, social networking, etc) will be served but the more electricity such a system will require if you're running it 24/7. A good compromise between performance and energy consumption is something like an old netbook. The battery of an old netbook or laptop even gives you UPS capability to keep the system going during brief power outages or cable re-arrangements, and that means using full disk encryption on the server also becomes more practical.

Welcome to the world of email. Email is really the archetypal decentralized service, developed during the early days of the internet. In principle anyone can run an email server, and that's exactly what you're doing with Freedombone. Email is very useful, but it has a big problem, and that's that the protocols are totally insecure. That made it easy for spammers to do their thing, and in response highly elaborate spam filtering and blocking systems were developed. Chances are that your emails are being blocked in this way. Sometimes the blocking is so indisciminate that entire countries are excluded. What can you do about it? Unless you control the block list at the receiving end you may not be able to do much unless you can find an email proxy server which is trusted by the receiving server.
