As a permanent requirement for all accounts, including changes as the user moves 
around -- long-term churn is 100% within relatively few years-- and to expect 
all domain owners who originally host a mailbox to then do this forwarding admin 
and ops competently, this is going to be a serious problem.

The scheme is certain to be quite unreliable along multiple axes.

Worse, I had not thought of Sheldon's excellent point about negative reputation 
blowback on the domain owner.

Per the followup comments on this, the domain owner might be able to do some 
things in domain name usage and IP Address assignment to mitigate this, the 
initial and on-going costs of getting this right and the likelihood of 
eliminating all blowback are problematic.
