Breaks current practices. 

This may be so. However, at a BoF in Montreal, Craig Spiezle said banks
were asking Microsoft to NOT DELIVER messages that failed SenderID
checks. I do believe he said the banks understood that may mean some
legitimate mail may not be delivered.

This is meant as a simple data point and nothing more.
