Trying to work with the big sites to get whitelisted is one way to fight this. Bogus registration emails are rarely the problem - usually, it's notification emails. Members sign up for new post notifications in various forums and threads, and then don't bother to unsubscribe. Instead, they report them as spam. Lazy morons? Yes. Problem for community sites? Absolutely.
