Sorry, your concern doesn't compile. You're worried about losing your domain and instead you've decided to worry about losing your address on someone else's domain?
Sounds to me like you're not fixing anything but just shuffling things around (probably in the wrong direction).
There's always the chance something can go wrong... either with your registrar or your email service provider. Personally, I'd just stick with a reputable registrar since it will also ease your concern w.r.t other things (e.g. web).
In addition, if your email service provider goes downhill, your registrar will be able to help you. The opposite does not hold true.
So, can you elaborate on why you think moving your email addresses will solve your problem? Any company can, after all, change policies or flake out; whether they do DNS or email doesn't really matter that much. But the fact remains that email relies on DNS, not vice versa.

Does this help or am I missing something?
