I agree that there may be transitional pain if a provider is cavalier about their approach to DKIM deployment, my thought that the market will work it out is more of a long term thought. I would also add that in my opinion, some types of providers are more likely to do things like this than others. I've got a fair investment of time, money, and intellectual energy in my current domain host. They aren't they cheapest by a long shot. They are also extremely unlikely, IMO, to foist something like this on their customers without warning. Businesses that use well established vendors with a solid reputation for focus on customer satisfaction have, I think, little to fear.
