I won't pimp the company I actually work for since that is more than likely against list rules but you can get reliable hosting if you only need the mailserver for pretty dang cheap. You don't even need to register a domain, just use the IP of the server and you are good to go. This is about the only solution. I fight with the blocklists every day in the course of work and they are no fun, I have come to really hate them. They may have a good concept behind them, but the implementation really bites, and they don't seem to care even one tiny bit.
