Name an ISP that will allow non-filtered TCP port 25 traffic for a non-business account to go through.
A $5 reverse proxy with a cloud/colo IP goes a long way (so you can map 25 -> whatever you like).
It does mean your traffic is centralized through a data center, but it probably goes through one already...
