The reason is so the you can type mail <username> and have it end up at the
right place. i.e. you don't need to know the mail domain to send a mail to
the local user. They also fix the from address so that if the message is
forwarded offsite, the reply still makes it.

Well, it would be a bug to qualify random addresses received in headers. But
when a message comes in, when is it allowed to qualify it and when not?

This is quite old behaviour and if you try to "fix" it, I wouldn't be
surprised if a large number of programs fail.
