I've got a 'Pi next to me now - which has open reverse ssh tunnels routing ports 25 and 465 from a DigitalOcean $5/month VPS to itself. (I'm working on getting Vagrant and Ansible set up so it can provison and configure inexpensive vpses and update dns MX records to suit on the fly…). The 'Pi lives behind my home NAT gateway - I can get to it's local network only port 443/ssl webmail if I vpn into my home network.

I'm experimenting with DigitalOcean, Hetzner, and NineFold (it's more about spreading out jurisdictions than absolutely minimising costs).
