I am considering purchasing a Raspberry Pi and hosting my own, as it seems worth the experience. However does it require that I have my own DNS server and a static IP address in order to connect to the mail server from anywhere in the world?
You really don't want to do that unless you have a friend at a hosting center who will let him plug your Pi into his rack and lend you a static IP. Getting static IPs at home these days is pretty much impossible unless you get very expensive business class cable service. Even if you have a static-ish IP on residential cable, nobody accepts mail directly from resi networks since it is about 99.99% botnet spam. On the other hand, it is the work of a moment to set up a $5/mo VPS running linux with a static IP at any of a long list of hosting providers like Tektonix or Digital Ocean or Linode. From your point of view, it's a linux box you can ssh into and manage the same way you'd manage linux on a small physical machine. R's, John
