If this is done right, it could become a centralised spam sender back-off system over multiple smtp servers. Maybe something for the future. We now pay $$$$ for a commercial system that implements this. 


The submission servers would need to share state with each others to make this reliable. Some nosql database would work for that I guess (memcached?)

Can you describe more fully what you would want it to do and/or what the current system does? Probably not something I'll implement soon, but would be good to know for future :)
