This is by design in some cases.  Email isn't only SMTP email. There are
still networks using X400 and no doubt other monsters. You don't type
an X400 address unless you really have to.  Reply is often the easiest
way to be sure of getting the address right, and in the case of an 
individual recipient they quite possibly not mind.  

Mailing lists are the exception.
