@statsguy It's a Raspberry Pi that does the house email. It used to do DHCP, DNS and VPN, but then I got a router that runs OpenWRT, which makes it easier to do those there. The router also runs the Asterisk VOIP phone system, which was mainly set up to block spam calls by demanding an extension number if you want to talk to a human. Voice mail gets wrapped up in an email and passed to the Pi. So really I've got two servers, I suppose.
