IMHO, and not specific to Postfix, too many issues come from not following 
standards and relying on software or tools that silently correct non-standard 
behavior. Then something is changed and stops the silent correction and doesn’t 
behave as expected or, as in this case, errors on the non-standard behavior. Do 
it right and then you won’t have to work around the problem again when the next 
change is made.
